The Swallow's Nest (Russian: Ласточкино гнездо, romanized: Lastochkino gnezdo, Ukrainian: Ластівчине гніздо, romanized: Lastivchyne hnizdo) is a decorative castle located at Gaspra, a small spa town between Yalta and Alupka on the Crimean peninsula. It was built between 1911 and 1912, on top of the 40-metre-high (130 ft) Aurora Cliff, in a Neo-Gothic design by the Russian architect Leonid Sherwood for Pavel Leonardovich von Steingel, a Russian noble with German roots.

The castle overlooks the Cape of Ai-Todor on the Black Sea coast and is located near the remains of the Roman castrum of Charax. The Swallow's Nest is one of the most popular visitor attractions in Crimea, having become the symbol of Crimea's southern coastline.

Ukraine is a country in Eastern Europe. It is the second-largest country in Europe after Russia, which borders it to the east and northeast. Ukraine also borders Belarus to the north; Poland and Slovakia to the west; Hungary, Romania and Moldova to the southwest; and the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city, followed by Kharkiv, Odesa, and Dnipro. Ukraine's official language is Ukrainian.

Humans have inhabited Ukraine since 32,000 BC. During the Middle Ages, it was the site of early Slavic expansion and later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. Kievan Rus' became the largest and most powerful realm in Europe in the 10th and 11th centuries, but gradually disintegrated into rival regional powers before being destroyed by the Mongols in the 13th century. For the next 600 years the area was contested, divided, and ruled by a variety of external powers, including the Grand Duchy of Lithuania, the Kingdom of Poland, the Polish–Lithuanian Commonwealth, the Austrian Empire, the Ottoman Empire, and the Tsardom of Russia.

Yalta (Ukrainian and Russian: Ялта) is a resort city on the south coast of the Crimean Peninsula surrounded by the Black Sea. It serves as the administrative center of Yalta Municipality, one of the regions within Crimea. Yalta, along with the rest of Crimea, is internationally recognised as part of Ukraine, and is considered part of the Autonomous Republic of Crimea. However, it is controlled de facto by Russia, which annexed Crimea in 2014 and regards the town as part of the Republic of Crimea. According to the most recent census, its population was 76,746 (2014 Census).

The city is located on the site of the ancient Greek colony of Yalita (Greek: Γιαλός, romanized: Gialós [ʝaˈlos̠]). It is said to have been founded by Greek settlers who were looking for a safe shore on which to land. It is situated on a deep bay facing south towards the Black Sea, surrounded by the mountain range Ai-Petri. It has a humid subtropical climate and is surrounded by numerous vineyards and orchards.

Yevpatoria (Ukrainian: Євпаторія, romanized: Yevpatoriia; Russian: Евпатория, romanized: Yevpatoriya; Crimean Tatar: Kezlev, Кезлев; Greek: Ευπατορία, romanized: Eupatoría) is a city in western Crimea, north of Kalamita Bay. Yevpatoria serves as the administrative center of Yevpatoria Municipality, one of the districts (raions) into which Crimea is divided. It had a population of 105,719 (2014 Census).

The Isthmus of Perekop, literally Isthmus of the Trench (Ukrainian: Перекопський перешийок; transliteration: Perekops'kyi pereshyiok; Russian: Перекопский перешеек; transliteration: Perekopskiy peresheek, Crimean Tatar: Or boynu, Turkish: Orkapı; Greek: Τάφρος; transliteration: Taphros), is the narrow, 5–7 kilometres (3.1–4.3 mi) wide strip of land that connects the Crimean Peninsula to the mainland of Ukraine. The isthmus projects between the Black Sea to the west and the Syvash to the east. The isthmus takes its name of "Perekop" from the Tatar fortress of Or Qapi.

The border between Ukraine's Autonomous Republic of Crimea and Kherson Oblast runs through the northern part of the isthmus. Since the start of the Russian military occupation and subsequent annexation of Crimea in 2014, this is also the de facto northern border of the Russian Republic of Crimea. The cities of Perekop, Armiansk, Suvorove (Crimea) [uk] and Krasnoperekopsk are situated on the isthmus. The North Crimean Canal ran through the isthmus, supplying Crimea with fresh water from the Dnieper River. Ukraine closed the canal in 2014, and the water supply was only partially replaced by other local and Russian sources.

Kherson Oblast (Ukrainian: Херсонська область, romanized: Khersonska oblast, IPA: [xerˈsɔnʲsʲkɐ ˈɔblɐsʲtʲ]; Russian: Херсонская область), also known as Khersonshchyna (Херсонщина, IPA: [xerˈsɔnʃtʃɪnɐ]), is an oblast (province) in southern Ukraine. It is located just north of Crimea. Its administrative center is Kherson, on the northern or right bank of the Dnieper river, which bisects the oblast. The oblast has an area of 28,461 km and a population of 1,001,598 (2022 estimate). It is considered the 'fruit basket' of the country, as much of its agricultural production is dispersed throughout the country, with production peaking during the summer months.

Most of the area of the oblast has been under Russian military occupation since early in the 2022 Russian invasion of Ukraine. In September 2022, Russia claimed to have annexed Kherson Oblast after arranging a disputed referendum. The referendum and the subsequent claimed annexation are internationally unrecognized. As the result of a counteroffensive operation, Ukrainian forces retook the whole area on the right bank of the Dnieper, including Kherson city, by mid-November 2022.

The Crimean Bridge (Russian: Крымский мост, romanized: Krymskiy most, IPA: [ˈkrɨmskʲij most]; Ukrainian: Кримський міст, romanized: Krymskyi mist), also called Kerch Strait Bridge or Kerch Bridge, is a pair of parallel bridges, one for a four-lane road and one for a double-track railway, spanning the Kerch Strait between the Taman Peninsula of Krasnodar Krai in Russia and the Kerch Peninsula of Crimea. Built by the Russian Federation after its annexation of Crimea at the start of 2014, the bridge cost ₽227.92 billion (US$3.7 billion) and has a length of 19 km (12 mi), making it the longest bridge in Europe and the longest bridge ever constructed by Russia.

In January 2015 the multibillion-dollar construction contract for the bridge was awarded to Arkady Rotenberg's Stroygazmontazh. Construction beganin February 2016. The road bridge was inaugurated by Russian president Vladimir Putin on 15 May 2018. It opened for cars on 16 May and for trucks on 1 October. The rail bridge was inaugurated on 23 December 2019 and the first scheduled passenger train crossed the bridge two days later. The bridge was opened for freight trains on 30 June 2020. A record amount of traffic, totalling 36,393 cars, was recorded on 15 August 2020.

The Arabat Spit (Ukrainian: Арабатська коса; Russian: Арабатская коса; Crimean Tatar: Arabat beli), or Arabat Arrow (Russian: Арабатская стрелка), is a barrier spit that separates the large, shallow, salty Syvash lagoons from the Sea of Azov. The spit runs between the Henichesk Strait in the north and the north-eastern shores of Crimea in the south. It is the largest of several spits of the Sea of Azov.

The Syvash or Sivash (Ukrainian and Russian: Сива́ш; Crimean Tatar: Sıvaş, Сываш, lit. 'dirt'), also known as the Putrid Sea or Rotten Sea (Russian: Гнило́е Мо́ре, romanized: Gniloye More; Ukrainian: Гниле́ Мо́ре, romanized: Hnyle More; Crimean Tatar: Çürük Deñiz), is a large area of shallow lagoons on the western edge of the Sea of Azov. Separated from the sea by the narrow Arabat Spit, the water of the Syvash covers an area of around 2,560 km (990 sq mi) and the entire area spreads over about 10,000 km (3,900 sq mi). The Henichesk Strait is its eastern connection to the Sea of Azov. The Syvash borders the northeastern coast of the main Crimean Peninsula. The central and eastern Syvash were registered as wetlands of Ukraine under the Ramsar Convention. Since the 2022 Russian invasion of Ukraine, the entire Syvash has been occupied by Russia.

The Southern Coast (Crimean Tatar: Yalı Boyu; Ukrainian: Півде́нний бе́рег, romanized: Pivdennyi bereg; Russian: Ю́жный бе́рег, romanized: Yuzhny bereg), also referred to as the Crimean Riviera, is a geographic region located in southern Crimea, a region internationally recognised as part of Ukraine but currently controlled by Russia. Stretching from Cape Aya to Kara Dag Mountain, the Southern Coast has a total length of about 180 km (110 mi). The Southern Coast has historically been a prominent tourist location due to its relatively warm climate and purported benefits for respiratory health, and drew an estimated 500,000 tourists yearly as of 1984.

The Pereiaslav Agreement or Pereyaslav Agreement (Ukrainian: Переяславська рада, romanized: Pereiaslavska Rada, lit. 'Pereiaslav Council', Russian: Переяславская рада) was an official meeting that convened for a ceremonial pledge of allegiance by Zaporozhian Cossacks to Russian tsar Alexis (r. 1645–1676) in the town of Pereiaslav in central Ukraine, in January 1654. The ceremony took place concurrently with ongoing negotiations that started on the initiative of Hetman Bohdan Khmelnytsky to address the issue of the Cossack Hetmanate with the ongoing Khmelnytsky Uprising against the Polish–Lithuanian Commonwealth and which concluded the Treaty of Pereiaslav (also known as the March Articles). The treaty itself was finalized in Moscow in April 1654 (in March according to the Julian calendar).

Khmelnytsky secured the military protection of the Tsardom of Russia in exchange for allegiance to the tsar. An oath of allegiance to the Russian monarch from the leadership of the Cossack Hetmanate was taken, shortly thereafter followed by other officials, the clergy and the inhabitants of the Hetmanate swearing allegiance. The exact nature of the relationship stipulated by the agreement between the Hetmanate and Russia is a matter of scholarly controversy. The council of Pereiaslav was followed by an exchange of official documents: the March Articles (from the Cossack Hetmanate) and the tsar's declaration (from Russia).

Lviv (/ləˈviːv/ lə-VEEV or /ləˈviːf/ lə-VEEF; Ukrainian: Львів [ˈlʲviu̯] ; Polish: Lwów [ˈlvuf] ; see below for other names) is the largest city in western Ukraine, as well as the fifth-largest city in Ukraine, officially with a population of 723,403 (2025 estimate). It serves as the administrative centre of Lviv Oblast and Lviv Raion, and is one of the main cultural centres of Ukraine. Lviv also hosts the administration of Lviv urban hromada. It was named after Leo I of Galicia, the eldest son of Daniel, King of Ruthenia.

Lviv (then Lwów) emerged as the centre of the historical regions of Red Ruthenia and Galicia in the 14th century, superseding Halych, Chełm, Belz, and Przemyśl. It was the capital of the Kingdom of Galicia–Volhynia from 1272 to 1340, when it went to King Casimir III the Great of Poland in a war of succession. In 1356, Casimir the Great granted it town rights. From 1434, it was the regional capital of the Ruthenian Voivodeship in the Kingdom of Poland. In 1772, after the First Partition of Poland, the city became the capital of the Habsburg semi-autonomous Polish-dominated Kingdom of Galicia and Lodomeria. From 1918, between the wars, the city was the centre of the Lwów Voivodeship in the Second Polish Republic. There it flourished in culture, industry and academia such as the Lwów School of Mathematics, the Lwów Historical School (Polish: lwowska szkoła historyczna) and the Lwów School of Economics. After the German-Soviet invasion of Poland in 1939, the massacre of Lwów professors took place, and Lwów was eventually annexed by the Soviet Union.

Dobruja or Dobrudja (US: /ˈdoʊbrʊdʒə/; Bulgarian: Добруджа, romanized: Dobrudzha or Dobrudža; Romanian: Dobrogea, pronounced [ˈdobrodʒe̯a] or [doˈbrodʒe̯a]; Turkish: Dobruca; Ukrainian and Russian: Добруджа, romanized: Dobrudzha) is a geographical and historical region in Southeastern Europe that has been divided since the 19th century between the territories of Bulgaria and Romania. It is situated between the lower Danube River and the Black Sea, and includes the Danube Delta, the Romanian coast, and the northernmost part of the Bulgarian coast. The territory of Dobruja is made up of Northern Dobruja, which is a part of Romania, and Southern Dobruja, which is a part of Bulgaria.

The territory of the Romanian region Dobrogea is organised as the counties of Constanța and Tulcea, with a combined area of 15,588 km (6,019 sq mi) and, as of 2021, a population of slightly less than 850,000. Its main cities are Constanța, Tulcea, Medgidia, and Mangalia. Dobrogea is represented by dolphins in the coat of arms of Romania.

The Danube Delta (Romanian: Delta Dunării, pronounced [ˈdelta ˈdunərij] ; Ukrainian: Дельта Дунаю, romanized: Del'ta Dunaju, pronounced [delʲˈtɑ dʊnɐˈju]) is the second largest river delta in Europe, after the Volga Delta, and is the best preserved on the continent. Occurring where the Danube River empties into the Black Sea, most of the Danube Delta lies in Romania (Tulcea County), with a small part located in Ukraine (Odesa Oblast). Its approximate surface area is 4,152 square kilometres (1,603 square miles), of which 3,446 km (1,331 sq mi) is in Romania. With the lagoons of Razim–Sinoe (1,015 km or 392 sq mi with 865 km or 334 sq mi water surface), located south of the main delta, the total area of the Danube Delta is 5,165 km (1,994 sq mi). The Razim–Sinoe lagoon complex is geologically and ecologically related to the delta proper; the combined territory is listed as a World Heritage Site.

Ukrainians (Ukrainian: українці, romanised: ukraintsi, pronounced [ʊkrɐˈjin⁽ʲ⁾ts⁽ʲ⁾i]) are an East Slavic ethnic group native to Ukraine. Their native tongue is Ukrainian, and the majority adhere to Eastern Orthodoxy, forming the second largest ethno-linguistic community. At around 46 million worldwide, Ukrainians are the second largest Slavic ethnic group after Russians.

Ukrainians have been given various names by foreign rulers, which have included Polish–Lithuanian Commonwealth, the Habsburg monarchy, the Austrian Empire, and then Austria-Hungary. The East Slavic population inhabiting the territories of modern-day Ukraine were known as Ruthenians, referring to the territory of Ruthenia; the Ukrainians living under the Russian Empire were known as Little Russians, named after the territory of Little Russia.

Rusyns, also known as Carpatho-Rusyns, Carpatho-Russians, Ruthenians, or Rusnaks, are an East Slavic ethnic group from the Eastern Carpathians in Central and Eastern Europe. They speak Rusyn, an East Slavic language variety, treated variously as either a distinct language or a dialect of the Ukrainian language. As traditional adherents of Eastern Christianity, the majority of Rusyns are Eastern Catholics, though a minority of Rusyns practice Eastern Orthodoxy.

Rusyns primarily self-identify as a distinct ethnic group and are recognized as such in all countries where they exist, with the exception of Ukraine, which officially classifies Rusyns as a sub-group of Ukrainians. In Croatia, Hungary, Poland, Romania, Serbia, and Slovakia, Rusyns have official minority status. Some Rusyns identify more closely with their country of residence (e.g. Polish, Slovak), while others self-identify as a branch of the Ukrainian people.

The romanization of Ukrainian, or Latinization of Ukrainian, is the representation of the Ukrainian language in Latin letters. Ukrainian is written in its own Ukrainian alphabet, which is based on the Cyrillic script. Romanization may be employed to represent Ukrainian text or pronunciation for non-Ukrainian readers, on computer systems that cannot reproduce Cyrillic characters, or for typists who are not familiar with the Ukrainian keyboard layout. Methods of romanization include transliteration (representing written text) and transcription (representing the spoken word).

In contrast to romanization, there have been several historical proposals for a Ukrainian Latin alphabet, usually based on those used by West Slavic languages, but none have been widely accepted.
