A Very Short History of ThessalonikiThessaloniki , in the Greek district of Central Macedonia, is, at about a million inhabitants, the second largest city in the country. More importantly, it is a city with a continuous 3000-year history, preserving relics of its Roman, Byzantine and Ottoman past and of its formerly dominant Jewish population. Its Byzantine churches, in particular, are included in UNESCO's World Heritage list.

The northernmost Byzantine walls of the city and parts of the western walls are still standing, as is the city's symbol - the White Tower, one of the 16th c. AD fortified towers - which is the only surviving tower on the seafront. The rest of the walls are in the picturesque old town (Upper Town) which offers a spectacular view over the bay, especially in the late afternoon. Take a walk along the enormous seafront promenade (about 12 km altogether) with views of the amphitheatrically-built city. See the Archaeological Museum, the new award-winning Museum of Byzantine Culture (2005 - the best Museum of Europe), the Roman Forum excavations.
Visit the upper town for its traditional old houses, small cobbled streets, Byzantine citadel, the Eptapyrgion fort.
The very lively and youth-oriented international film festival is held in November, the International Trade Fair in September. On no account should you miss the Byzantine churches built between the 5th and 14th century ACE, such as St Demetrios, (7th c. ACE) and Agia Sophia (Holy Wisdome, 9th c. ACE), and many lovely smaller ones in the upper town (St Nicolaos Orfanos is particularly worth a look for its frescoes), which are on the UNESCO World Heritage List. One of them, the Rotonda, started life as a Roman temple of Zeus, built by ceasar Galerius, and is almost as old as the Pantheon in Rome. Next to the Rotonda, see the Arch of Triumph of Galerius and the ruins of his palace.
