Edessa, Greece in the context of "Pella (regional unit)"

Aegae or Aigai (Ancient Greek: Αἰγαί) was the original capital of Macedon, the ancient kingdom of the Makedones in Emathia in northern Greece. The site is located on the foothills of the Pierian Mountains, between the modern towns of Vergina and Palatitsia, and overlooks the Central Macedonian Plain. The city was abandoned in the 3rd century and was rediscovered in the 19th.

Three major archaeological missions have been carried out at Aegae. The first was led by Léon Heuzey of the French School at Athens in the 1860s; Manolis Andronikos led excavations over a century later and made many important discoveries, including the tomb of Philip II and the Golden Larnax bearing the Vergina Sun; and Angeliki Kottaridi [el] led restoration efforts in the 2000s. Today it is the site of an archaeological site and two museums. Prior to the discoveries at Vergina, Edessa was thought to be the site of Aegae.

Edessa (/əˈdɛsə/; Ancient Greek: Ἔδεσσα, romanized: Édessa) was an ancient city (polis) in Upper Mesopotamia, in what is now Urfa or Şanlıurfa, Turkey. It was founded during the Hellenistic period by Macedonian general and self proclaimed king Seleucus I Nicator (r. 305–281 BC), founder of the Seleucid Empire. He named it after an ancient Macedonian capital. The Greek name Ἔδεσσα (Édessa) means "tower in the water". It later became capital of the Kingdom of Osroene, and continued as capital of the Roman province of Osroene. In Late Antiquity, it became a prominent center of Christian learning and seat of the Catechetical School of Edessa. During the Crusades, it was the capital of the County of Edessa.

The city was situated on the banks of the Daysan River (Ancient Greek: Σκίρτος; Latin: Scirtus; Turkish: Kara Koyun), a tributary of the Khabur, and was defended by Şanlıurfa Castle, the high central citadel.

Eordaea (also spelled Eordaia or Eordia, Greek: Ἐορδαία) was a geographical region of Upper Macedonia and later an administrative region of the kingdom of Macedon. Eordaea was located south of Lynkestis, west of Emathia, north of Elimiotis, and east of Orestis. It was incorporated into the Argead kingdom of Macedon earlier than the rest of Upper Macedonia.

Eordaea stretched in the basin of Eordaia, the current homonymous municipality in Greece, which is named after the ancient region, and also in the southern part of the municipality of Amyntaio and the western part of the municipality of Edessa.

John Komnenos Doukas (Greek: Ιωάννης Κομνηνός Δούκας, Iōannēs Komnēnos Doúkas), Latinized as Comnenus Ducas, was ruler of Thessalonica from 1237 until his death in 1244.

John was the eldest son of Theodore Komnenos Doukas and Maria Petraliphaina. In 1230 his father was captured together with his family in the Battle of Klokotnitsa by Ivan Asen II of Bulgaria. When his sister Irene married Ivan Asen II in 1237, John was released from captivity together with his now blind father Theodore and his younger brother Demetrios. Theodore and his sons made their way back to Thessalonica and incited a revolt against Theodore's brother Manuel Komnenos Doukas who had ruled the city since 1230. Since Theodore was blind, he installed his son John as ruler and retired to Vodena.

Pozar thermal baths (Greek: Λουτρά Πόζαρ) are located 32 km north of Edessa and 13 km west of Aridaia in the region of Macedonia, Greece.

The baths are naturally heated at 37 °C (99 °F) and are a popular tourist attraction in the cooler months.

The railway from Thessaloniki to Bitola is a 219 kilometres (136 mi) long railway line, that connects the port city Thessaloniki in Greece with Bitola in the Republic of North Macedonia, via Veroia, Edessa, Amyntaio and Florina. The line was opened in 1894 under the name "Société du Chemin de Fer ottoman Salonique-Monastir", when the area was part of the Ottoman Empire. The section between the international border and Bitola is not used anymore, and as of 2025 passenger services are restricted to the section between Thessaloniki and Florina. Makedonski Železnici also operates a daily service from Žabeni to Bitola and onwards to Skopje. The easternmost section of the line, Platy–Thessaloniki, is part of the important connection towards Athens and Northern Greece.
