Plovdiv's Regional Archaeological Museum is the place to go when the Roman theatre and old-town houses have made you curious about what lies underneath the city. The collection reaches back into prehistory and Thracian culture, then follows the region through Greek, Roman, and medieval periods.
The Thracian material is the highlight, especially the metalwork and grave finds that show how wealthy the surrounding plains could be. It is a relatively compact museum, but it adds depth to a city where ancient remains are scattered through everyday streets.
