Thessaloniki (520 km. north of Athens) is the second largest city of Greece and the most important centre of the area. Built near the sea (at the back of the Thermaïkos Gulf), it is a modern metropolis bearing the marks of its stormy history and its cosmopolitan character, which give it a special beauty and charm.The ancient forum (dated to the late 2nd or the early 3rd century AD) with squares, porticoes, additional buildings and odeum (293-395 AD), the palace complex of Galerius Maximianus (4th c. AD), the thermae, the hippodrome, the temples and other monuments and moveable finds (among them mosaics of exquisite art) brought to light in excavations and surveys. In the south square, is the famous Stoa of the Idols, which was two-storeyed and lavishly decorated.Thessaloniki, with its host of Byzantine monuments (due to it’s significance during the Byzantine period), justifiably is considered an open-air museum of Byzantine art.
