Thessaloniki wears its history on its sleeve, from prehistory until today. For the former, visit the city’s Archaeological Museum, a receptacle of much of Greece’s treasures from the Macedonian and Hellenic periods. The Rotunda and Arch of Galerius are the remnants of a planned mausoleum for the 4th century Emperor, who missed out by dying elsewhere. The Rotunda was later ordained as a church by Constantine and later a mosque by the Ottomans. The 15th century White Tower is an iconic landmark of the city, and has been ingeniously included in the New Waterfront mixed-use development that invites a stroll through a triumph of modern public planning along an ancient seashore.
