Triagalna kula na Serdika

Long forgotten beneath the surface of modern Sofia, the Triangular Tower of Serdica today stands as one of the most impressive testaments to the city's rich Roman past. Cleverly integrated into the underground level of the modern Serdica metro station and the Museum of Sofia History, this fortress tower offers a unique glimpse into ancient history, literally blended with the pulse of today's city. As part of the western defensive wall of ancient Serdica, the tower was a fortification structure likely erected in the 2nd-4th centuries to guard the city's western entrance – one of its most important thoroughfares. Its triangular shape is not only architecturally interesting but also functionally effective against attacks, providing greater visibility and resilience. Today, visitors can wander among the well-preserved ruins, grasp the scale of the ancient constructions, and imagine life in Serdica centuries ago. The site is integrated in a way that allows easy access and provides informational panels recounting the tower's history and its significance within the context of the Roman city. Excavations around the tower also reveal parts of the fortress wall and other ancient structures, creating a comprehensive picture of the fortified city. A visit to the Triangular Tower is a must for anyone wishing to delve into Sofia's layered history and witness how the ancient and modern coexist harmoniously under one roof – or rather, under one metro station. It is a true underground museum that reminds us of the grandeur of Serdica.
