While northern Greece is not the most popular destination for the average traveler, there are many places of interest to explore. Diversity should be northern Greece's second name – the region stretches across more cultures and terrains than any other in the country. Mighty civilisations, including Macedonians, Thracians, Romans, Byzantines, Slavs and Turks, have left traces here. From the tomb of the royal family of the Macedonian empire to the place where St. Paul first preached and from the rocky formation of Meteora to the second largest city of Greece, one can discover the many secrets of the land.
