Museo Diocesano Bari

The succorpo is an archaeological site and museum down to as much as 5 meters below the cathedral of Bari. This museum does as good a job as I've seen anywhere at showing the strata of history as one level is built upon an older one. Visible here are remnants of the Roman period, the early Christian through the early and later medieval to the modern periods.
The 1st place one encounters in the succorpo is the remains of the 5th century basilica. The 1st picture is of the Timoteo mosaic, so called for the name in the inscription (white and black, a bit left of center). The 2nd picture is a bit of original fresco that shows part of a person dressed in bishops robes.
The 3rd picture is of ruins from the early medieval period before the current cathedral was raised, beginning in the 12th century.
The 4th picture looks through some medieval arches over ancient walls that date to Roman times.
After the current cathedral was raised, these older spaces were used for burials. The 5th and 6th pictures are in such spaces. They are likely from different time periods of construction, given the differences in the structuresBaca lagi
