Administrative centre in the context of "Urban districts of Ukraine"

A seat of government is a "building, complex of buildings or the city from which a government exercises its authority". When referring to a city, the seat of government is generally the capital of the state or administrative entity in question, although there are exceptions. Particular terms for the seat of certain territorial subdivisions are administrative centre, county seat (common in the United States), county town (United Kingdom and Ireland), or barrio-pueblo (Puerto Rico), among others; buildings that may function as seats of government include official residences, supreme court buildings, city or town halls, administrative or executive buildings, shire or county halls, legislative buildings, and barangay halls.

Sparta was a prominent city-state in Laconia in ancient Greece. In antiquity, the state was known as Lacedaemon (Λακεδαίμων, Lakedaímōn), while "Sparta" referred to its capital, a group of villages in the valley of the Evrotas River in Laconia, in southeastern Peloponnese. Around 650 BC, it rose to become one of the major military powers in Greece, a status it retained until 371 BC.

Sparta was recognized as the leading force of the unified Greek military during the Greco-Persian Wars, in rivalry with the rising naval power of Athens. Sparta was the principal enemy of Athens during the Peloponnesian War (431–404 BC), from which it emerged victorious after the Battle of Aegospotami. Thebes' victory over Sparta at the Battle of Leuctra in 371 BC ended Spartan hegemony and freed Messenia from Spartan rule; the loss of the slave labor this region provided sent the city into terminal decline as a military power, though it retained its independence until its forcible integration into the Achaean League in 192 BC. The city recovered some autonomy after the Roman conquest of Greece in 146 BC and became a tourist destination during the Roman era, restoring some measure of prosperity. However, Sparta was sacked in 396 AD by the Visigothic king Alaric, and underwent a long period of decline into the medieval period, when much of its population relocated to Mystras. Modern Sparta is a provincial town and the seat of the Laconia regional administration.

Rome is the capital city and most populated comune (municipality) of Italy. It is also the administrative centre of the Lazio region and of the Metropolitan City of Rome. A special comune named Roma Capitale with 2,746,984 residents in 1,287.36 km (497.1 sq mi), Rome is the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome Capital, with a population of 4,223,885 residents, is the most populous metropolitan city in Italy. Its metropolitan area is the third-most populous within Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber Valley. Vatican City (the smallest country in the world and headquarters of the worldwide Catholic Church under the governance of the Holy See) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city. Rome is often referred to as the City of Seven Hills due to its geography, and also as the "Eternal City". Rome is generally considered to be one of the cradles of Western civilization and Western Christian culture, and the centre of the Catholic Church.

Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it a major human settlement for over three millennia and one of the oldest continuously occupied cities in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by many as the first-ever Imperial city and metropolis. It was first called The Eternal City (Latin: Urbs Aeterna; Italian: La Città Eterna) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called Caput Mundi (Capital of the World).

Odesa, also spelled Odessa, is the third most populous city and municipality in Ukraine and a major seaport and transport hub located in the south-west of the country, on the northwestern shore of the Black Sea. The city is also the administrative centre of the Odesa Raion and Odesa Oblast, as well as a multiethnic cultural centre. As of January 2021, Odesa's population was approximately 1,010,537. On 25 January 2023, its historic city centre was declared a World Heritage Site and added to the List of World Heritage in Danger by the UNESCO World Heritage Committee in recognition of its multiculturality and 19th-century urban planning. The declaration was made in response to the bombing of Odesa during the Russian invasion of Ukraine, which has damaged or destroyed buildings across the city.

In classical antiquity a large Greek settlement existed at its location no later than the middle of the 6th century BC. It has been researched as a possible site of the ancient Greek settlement of Histria. The first chronicle mention of the Slavic settlement-port of Kotsiubijiv, which was part of the Grand Duchy of Lithuania, dates back to 1415, when a ship was sent from here to Constantinople by sea. After the Grand Duchy lost control, the port and its surroundings became part of the domain of the Ottoman Empire in 1529, under the name Hacibey, and remained in it until the Ottomans' defeat in the Russo-Turkish War (1787–1792). In 1794, a decree of the Russian empress Catherine II was issued to establish a navy harbor and trading place in Khadjibey, which was named Odessa soon after. From 1819 to 1858, Odesa was a free port. During the Soviet period, it was an important trading port and a naval base. During the 19th century, Odesa was the fourth largest city of the Russian Empire, after Moscow, Saint Petersburg and Warsaw. Its historical architecture is more Mediterranean than Russian, having been heavily influenced by French and Italian styles. Some buildings are built in a mixture of different styles, including Art Nouveau, Renaissance and Classicist.

Preston (/ˈprɛstən/ ) is a city on the north bank of the River Ribble in Lancashire, in North West England. The city is the administrative centre of the county of Lancashire and the wider City of Preston local government district. Preston and its surrounding district obtained city status in 2002, becoming England's 50th city in the 50th year of Queen Elizabeth II's reign. Preston had a population of 147,835 at the 2021 census, the City of Preston district 156,411 in 2023 and the Preston Built-up Area 313,322. The Preston Travel To Work Area, in 2011, had a population of 420,661, compared with 354,000 at the previous census. The south bank of the Ribble is part of the Preston urban area, although it forms the South Ribble borough that is administratively separate.

Preston and its surrounding area have provided evidence of ancient Roman activity, largely in the form of a Roman road that led to a camp at Walton-le-Dale. The Angles established Preston; its name is derived from the Old English meaning "priest's settlement" and in the Domesday Book is recorded as "Prestune". In the Middle Ages, Preston was a parish and township in the hundred of Amounderness and was granted a Guild Merchant charter in 1179, giving it the status of a market town. Textiles have been produced since the mid-13th century when locally produced wool was woven in people's houses. Flemish weavers who settled in the area in the 14th century helped develop the industry. In the early-18th century, Edmund Calamy described Preston as "a pretty town with an abundance of gentry in it, commonly called Proud Preston". Sir Richard Arkwright, inventor of the spinning frame, was born in the town. The most rapid period of growth and development coincided with the industrialisation and expansion of textile manufacturing. Preston was a boomtown of the Industrial Revolution, becoming a densely populated engineering centre, with large industrial plants. The town's textile sector fell into terminal decline from the mid-20th century and Preston has subsequently faced similar challenges to other post-industrial northern towns, including deindustrialisation, economic deprivation and housing issues.
