Heptapyrgion Fortress | Thessaloniki

The Heptapyrgion Fortress, also known as the Yedi Kule (meaning "Seven Towers" in Turkish), is a significant historical landmark in Thessaloniki, located at the highest point of the Ano Poli (Upper Town) neighborhood. This Byzantine and Ottoman fortress served as a crucial military stronghold and later as a notorious prison, giving it a complex and layered history.

Historical Overview:

• Byzantine Beginnings: The original construction of Heptapyrgion dates back to the Byzantine era (4th century), when Thessaloniki was a key city in the Byzantine Empire. It was built as part of the city’s defensive wall system to protect against invasions and played a strategic role given its elevated position, overlooking the city and the Thermaic Gulf.
• Ottoman Era: In the 15th century, after the Ottoman conquest of Thessaloniki, the fortress was reinforced and renamed Yedi Kule. The Ottomans added elements to strengthen it, making it one of the main military strongholds in Thessaloniki.
• Prison Function: Starting in the late 19th century and continuing until 1989, Heptapyrgion functioned as a prison, notorious for its harsh conditions. During the Greek Civil War (1946–1949) and the military junta in the 1960s and 70s, it housed political prisoners, giving it a grim reputation and emotional significance in Greek history.

Architecture and Structure:

• Seven Towers: True to its name, Heptapyrgion has seven distinct towers connected by thick, fortified walls. These towers were designed for military defense, allowing soldiers to monitor and protect the city.
• Mix of Byzantine and Ottoman Influences: The fortress reflects both Byzantine and Ottoman architectural styles, with original Byzantine walls and towers later modified by Ottoman additions, including arched gateways and thick stone walls.
• Inner Courtyard and Cells: The fortress’s large central courtyard was used as a barracks and, later, a prison yard. The cells are austere and confined, giving insight into the difficult conditions endured by prisoners over the decades.

Key Features:

• Panoramic Views: Positioned on a hilltop, the fortress offers stunning views over Thessaloniki, the sea, and surrounding areas, making it a popular spot for visitors and photographers.
