The Acropolis of Thessaloniki lies in the northernmost part of the city, enclosed by the walls, just beyond Vlatodon Monastery. Two massive gates, called ‘portares’ lead into the Acropolis. The Tower of Trigonio, a medieval-era arsenal and weaponry that now offers a stunning view of Mount Olympus, also stands here.
Although the Acropolis of Athens is the more world-famous one, every Greek city had a region distinguished as an ‘Acropolis’. The term referred to the uppermost part of a city along the slope of a mountain with a citadel. Thessaloniki’s Acropolis surrounds the citadel Heptapyrgion, a Byzantine and Ottoman-era fortress that was later turned into the notorious Yedikule prison.
