The Thick Tower was built on the site of a previous defensive tower that collapsed during a severe storm.
Thalia Hall, housed within the structure, was the first permanent theater venue in Sibiu, founded in 1788 by Martin Hochmeister.
The tower's original design included thick, solid walls specifically engineered to withstand artillery fire.
The building suffered a devastating fire in 1949 that left it in ruins for decades before a major restoration project began in the early 2000s.
Architectural restoration successfully blended the 16th-century fortress walls with a modern glass-and-steel concert hall structure.
The Thick Tower, known as Turnul Gros, is a 16th-century fortification located on the southern edge of Sibiu's medieval defensive wall. Constructed between 1540 and 1542, it served as a key defensive bastion for the city. In the 18th century, the structure was repurposed to house Thalia Hall, which became the site of the first theatrical performances in Sibiu. The building now serves as the headquarters and concert venue for the Sibiu State Philharmonic. The original masonry and heavy defensive architecture remain visible alongside its modern function as a performance space. It is situated directly adjacent to the city's surviving fortification systems and the Bulevardul Corneliu Coposu.
