The Small Basilica of Philippopolis (Bulgarian: Малка базилика на Филипопол, Malka bazilika na Filipopol) is one of Plovdiv's most distinctive landmarks. The basilica is located on Maria Louisa Blvd in the central part of Bulgaria's second-largest city. The ruins of the early Christian church were found during construction works in the area in 1988. The three-nave basilica is an example of the exceptional skill of mosaic builders in ancient Philippopolis.
