Built on top of three of the city’s 6 syenite hills, the Old Town is a historical and architectural reserve of great cultural significance. The buildings done in the Bulgarian Revival Period Architectural Style, the various statues and monuments, and the pieces of ancient Roman architecture scattered around the Old Town form a rich tapestry of several historical periods, forming a mural that offers a valuable insight into multiple cultures and their lifestyle, preserving them for future generations to see. The most famous landmarks in the Old Town are the Roman theatre, Balabanov and Hyndlian houses, and Hissar Kapia.
