Ancient Plovdiv Architectural and Historical Reserve (The Old Town) is located in the Central part of the city of Plovdiv on the Three Hills (Nebet Tepe, Taksim Tepe and Dzhambaz Tepe) and covers an area of about 35 ha. It was formed due to the continuous life over the centuries – from Prehistoric, Thracian, Hellenic, Roman, Late-ancient, Medieval, National Revival, and Post-Liberation periods to present days. The combination of the prevailing Antiquity, Middle Ages and Revival in an independent core within the modern city is one of a kind for our country. From the Roman and the Late-ancient period in the Old Town have been best preserved the Ancient Theatre, the Ancient Forum, the Roman Stadium, Early Christian basilicas, public and private buildings, pipelines, street network and parts of the fortress walls, constructed in the Antiquity and the Middle Ages. From the National Revival period the authentic architecture of houses as well as several churches and school buildings have been preserved. The residential buildings are divided into two main groups. The first group of houses corresponds to the mountain asymmetrical type, but it has been expanded and enriched for the needs of the urban life. The second group is the so-called “Plovdiv symmetrical urban house”. This group of buildings is characterized by a unique national interpretation of the European baroque. http://www.visitplovdiv.com/en/node/676
