I suspect that many other churches would find much older churches buried beneath/within them. In Augsburg GE, excavations beneath the main cathedral there (the Dom) uncovered a 3-4th century church.

There is one just out of Eeast of Tarsus (about 15 - 20 KM) founded by Paul which is well known - known as the blue temple. I know because I have been in the temple. Only the walls remain and a small circular platform in the center where the speaker would sit and preach.

It must have been an incredible experience seeing where the Apostle Paul preached and taught. I hope to go there some day.

At the Dom in Augsburg, the building is intact. the rooms were filled in with dirt. artwork is still present on the walls. Most remarkable find in itself.
