Cella Septichora
Situated in a serene little park in front of Pécsi Bazilika, this subterranean museum—and UNESCO World Heritage site—is home to a series of burial chambers, many with remarkably well-preserved religious murals. The burial site dates back to when Pécs was a Roman outpost called Sopianae, though it was located just outside the city walls (as was the custom). Today, the excavated crypts are linked with a series of suspended metal walkways to help preserve them from damage. Two are of particular note: the beautifully decorated Wine Pitcher Burial Chamber, with its paintings of vines and drinking vessels (best seen from above); and the chapel-like Peter and Paul Burial Chamber, covered in Christian symbols and colorful frescoes (best seen from below).
A "Time Traveler" ticket also gets you into the nearby Early Christian Mausoleum, a tomb with stunning murals of Adam and Eve, Daniel in the Lion's Den, and the Resurrection, as well as the Medieval University.
