Explore the port city of Thessaloniki on a guided trip departing from the Halkidiki area. Take a panoramic drive through the Old Town to discover the remnants of its Roman, Byzantine and Ottoman history, then visit a couple of major landmarks to get a deeper understanding of the city's heritage. Depart early in the morning from your location in Kassandreia or Sithonia and begin the city tour with a panoramic drive around the White Tower. Keep driving toward the main landmarks of the city, including the Galerius Arch, the Rotunda monument, the Old Town, and the City Walls. Receive an insightful commentary from your expert guide as you look at each of these buildings, then move on to your first stop. Visit Agios Demetrius Byzantine Church, the most important one in Thessaloniki for religious, historical, and artistic reasons. See the ancient underground crypt. Before going back, stop at the Archaeological Museum, which holds different artifacts from the archaic, classical, Hellenistic, and Roman periods, mostly from the city of Thessaly.
