Thessaloniki is the second-largest city in Greece, with over 1 million inhabitants in its metropolitan area, and the capital of Macedonia. The city of Thessaloniki was founded in 315 BC by Cassander of Macedon. 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 passed from the Ottoman Empire to Greece on 8 November 1912. Thessaloniki is a popular tourist destination in Greece. In 2013, National Geographic Magazine included Thessaloniki in its top tourist destinations worldwide. After the 2nd World War Thessaloniki was rebuilt with large-scale development of new infrastructure and industry throughout the 1950s, 1960s and 1970s. Many of its architectural treasures still remain, adding value to the city as a tourist destination, while several early Christian and Byzantine monuments of Thessaloniki were added to the UNESCO World Heritage list in 1988. The climate is mainly Mediterranean but because there is a small amount of rain in the summer it doesn't qualify as such, but in general winters are cool and wet and summers are hot and dry.
