The Architectural and Historical Reserve Ancient Plovdiv is a cultural phenomenon that has been shaped over centuries. It has preserved more than 200 immovable cultural monuments from seven historical periods: Prehistoric, Thracian, Hellenistic and Roman, Medieval, National Revival, and the 20th century. It is located in the central part of Plovdiv, situated on the Three Hills (Nebet, Taksim, and Dzhambaz Tepe), and covers an area of approximately 35 hectares. Within the reserve are located unique monuments such as the Archaeological Complex Nebet Tepe, the Ancient Theatre, the architectural and historical ensemble of Hisar Kapia, as well as a series of street ensembles with fully preserved old architecture. Admiration is inspired by the houses of Argir Kuyumdzhioglu, Dimitar Georgiadi, Nikola Nedkovich, Stepan Hindliyan, Georgi Mavridi (Lamartin House), Georgi Klianti, Luka Balabanov, as well as the Orthodox churches "The Holy Assumption Cathedral" (Uspenie Bogorodichno church), "St. St. Constantine and Helena", "St. Martyr Marina", “Saint Nedelya”, and many others. The interior of these houses impresses with its artistic decoration and remarkably well-preserved original frescoes and furniture. More than 20 of the Revival-period houses are currently used as museums and galleries, and are recognized by experts as the peak of 19th-century architectural development in Bulgaria. During this period, a distinct architectural style emerged, known as the Plovdiv Baroque. The reserve also hosts private galleries and numerous craft workshops. In 1979, the Architectural and Historical Reserve Ancient Plovdiv was awarded the Golden European Medal for the Preservation of Historical Monuments.
