The Rennaissance town of Old Plovdiv was built during the 19th century. Today it has survived as a unique architectual ensemble on the three hills. Its houses reveal the remarkable urban culture of Bulgarian builders, as well as their sense of harmony and their creative power. The brilliant architecture with its noble, stylish simplicity could be called rightfully the Baroque of Plovdiv. The Bulgarian people have always been proud that Old Plovdiv was restored and preserved as a large open museum in order to stay for future generations. Today Old Plovdiv is an autonomous area within the modern town with a municipality of its own. It is declared an architectural museum reserve with over 150 monuments of culture - houses from the National Revival period.
