Once part of the Roman, Byzantine and Ottoman Empires, this Greek port city has a rich history which is just waiting to be discovered. Many monuments have been listed as UNESCO World Heritage Sites, with some of the mosaics considered great masterpieces of Early Christian art. Hop off at the Church of Agios Dimitrios for one of the most famous examples.
This tour includes the White Tower of Thessaloniki, or Lefkós Pýrgos. Undoubtedly the most famous landmark in the city, this 15th-century Ottoman tower stands on the waterfront and offers fantastic views across the bay. From the old to the new, continue along the promenade to see one of the most photographed sculptures in Thessaloniki. Zongolopoulos' Umbrellas, a more modern installation near the Makadonia Palace Hotel, make for a fantastic photo at sunset.
Hop back on the bus as it takes you to Ano Poli, Thessaloniki's Upper Town, located around the acropolis. Arguably one of the most beautiful areas and in fact, the only historic neighbourhood to survive the Great Fire of 1917, it's worth hopping off here and wandering through the streets, admiring the traditional architecture and unbeatable views. If you want to keep on exploring, you might want to climb to the upper part of the Old Town to visit the Heptapyrgion, the Byzantine fortress which overlooks the city.
