Plovdiv Amphitheater is a beautifully preserved Roman site which dates back to the 2nd century AD, during the reign of the Emperor Trajan. Although known as Plovidiv Amphitheater, it is in fact an ancient theater, not an amphitheater. It would remain in use for several hundred years, right up until the 5th century AD. Also known as Trimontium Amphitheater, at its peak Plovdiv Amphitheater could have seated between 6,000 and 7,000 people. Rediscovered in the 1970s, this magnificent site still plays host to events throughout the year.
