Plovdiv’s magnificent 2nd-century-AD amphitheatre, built during the reign of Emperor Trajan, was only uncovered during a freak landslide in 1972. It once held about 6000 spectators. Now largely restored, it's one of Bulgaria's most magical venues, once again hosting large-scale special events and concerts. Visitors can admire the amphitheatre for free from several lookouts along ul Hemus, or pay admission for a scarper around.
