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.
“APSE”
In architecture, the apse (Latin absis “arch, vault”; sometimes written apsis; plural apses) is a semicircular recess covered with a hemispherical vault. In Romanesque, Byzantine and Gothic Christian abbey, cathedral and church architecture, the term is applied to the semi-circular or polygonal section of the sanctuary at the liturgical east end beyond the altar. Geometrically speaking, an apse is either a half-cone or half-dome.
The epithet “apsidal” may be applied to the exedra of classical architecture, a feature of the secular Roman basilica, which provided some prototypes for Early Christian churches. The apse in the Roman basilica was often raised (as the sanctuary generally still is) as a hieratic feature that set apart the magistrates who deliberated within it.
A simple apse set into the east end of an English parish church, at Poulton-le-Fylde, Lancashire.
The decorated apses of the Cathedral of Monreale, Sicily.
Fresco within the apse of an Orthodox church.The apse as a semicircular projection (which may be polygonal on the exterior, or reveal the radiating projections of chapels) may be roofed with a half-dome or with radiating vaulting. A simple apse may be merely embedded within the wall of the east end. Eastern orthodox churches may have a triple apse, which is usually a mark of Byzantine influence when it is seen in Western churches.
Smaller subsidiary apses may be found around the choir or even at the ends of transepts. An exedra or apse may be reduced in scale to form a niche within the thickness of walling; a niche does not reveal its presence by projecting on the exterior. Where an apse contains an altar or throne it can be architecturally referred to as a tribune.
The interior of the apse is traditionally a focus of iconography, bearing the richest concentration of mosaics, or painting and sculpture, towards which all other decoration may tend.
This would make it an older established church than the ones in Macedonia and Rome who claim primacy.
