Salonika, Central Macedonia, Greece

🇬🇷 Thessaloniki (Θεσσαλονίκη, also known as Thessalonica, Saloniki, or Salonica, is the second-largest city in Greece, with over one million inhabitants in its metropolitan area, and the capital of the geographic region of Macedonia, the administrative region of Central Macedonia and the Decentralized Administration of Macedonia and Thrace. It is also known in Greek as η Συμπρωτεύουσα (i Symprotévousa), literally "the co-capital", a reference to its historical status as the Συμβασιλεύουσα (Symvasilévousa) or "co-reigning" city of the Byzantine Empire alongside Constantinople.

Thessaloniki is located on the Thermaic Gulf, at the north-west corner of the Aegean Sea. It is bounded on the west by the delta of the Axios. It is Greece's second major economic, industrial, commercial and political centre, and a major transportation hub for Greece and south-eastern Europe, notably through the Port of Thessaloniki. The city is renowned for its festivals, events and vibrant cultural life in general, and is considered to be Greece's cultural capital. Events such as the Thessaloniki International Fair and the Thessaloniki International Film Festival are held annually, while the city also hosts the largest bi-annual meeting of the Greek diaspora. Thessaloniki was the 2014 European Youth Capital.

The city was founded in 315 BC by Cassander of Macedon, who named it after his wife Thessalonike, daughter of Philip II of Macedon and sister of Alexander the Great. An important metropolis by the Roman period, Thessaloniki was the second largest and wealthiest city of the Byzantine Empire. It was conquered by the Ottomans in 1430 and remained an important seaport and multi-ethnic metropolis during the nearly five centuries of Turkish rule. It passed from the Ottoman Empire to the Kingdom of Greece on 8 November 1912. Thessaloniki exhibits Byzantine architecture, including numerous Paleochristian and Byzantine monuments, a World Heritage Site, as well as several Roman, Ottoman and Sephardic Jewish structures. The city's main university, Aristotle University, is the largest in Greece and the Balkans.

Thessaloniki is a popular tourist destination in Greece. In 2013, National Geographic Magazine included Thessaloniki in its top tourist destinations worldwide, while in 2014 Financial Times FDI magazine (Foreign Direct Investments) declared Thessaloniki as the best mid-sized European city of the future for human capital and lifestyle.
