Cathedral Excavations Museum / Residenzplatz
The Cathedral Excavations Museum under the Residenz and Domplatz in the area of the present cathedral provides a view into building activities since Roman times. Especially impressive are the archaeological excavation finds of a Roman villa; various walls, architectural parts, mosaics, drains and hot-air heating systems were brought to light.
Also on view are foundations and wall remnants of the west tower of the Romanesque cathedral built under Archbishop Konrad III in the late twelfth century; the cathedral was demolished after a fire (1598).
