The White Tower is the most iconic symbol of the city. The tower was constructed by the Ottomans sometime in the early 15th century and once guarded the eastern end of the city's sea walls. In the 19th century, this tower was used as a notorious prison. Nowadays, it is a welcoming museum of art and local history. The museum offers a rapid lesson in the history of the city. Ideally, you'll take in this well-dosed overview before continuing to the more specialised museums and archaeological sites. For best results, grab the free audio guide at the entrance. The last floor of the tower gives you a wonderful view of the city.

While exploring the historic Ano Poli, the Old City or Upper Town, you will stumble upon the old city wall and the Heptapyrgion. It is a Byzantine and Ottoman-era fortress.

Enjoy your urban hike up to the monument, check out the panoramic views and sip a frappe in one of the charming cafes in the area. Also known as Edy Kulѐ or Eptapirgio, 'Seven Towers', is a medieval fortress with towers in the northeastern part of Thessaloniki. Despite its name, the fortress has ten towers. The fortress was built in the IX century, and some parts of it were built later. Like the White Tower, it was used as a prison from the late 19th century until 1978.
