of limestone blocks, but no superstructure came to light. It may have had a cultic function because it is characterised by the same curious orientation as the temple of Apollo (or it was used as a propylon). Above the substructure was a small church built in Byzantine times which has seen several reconstructions up until the 19th century. Churches The most famous church of Didyma stood in the sekos of the temple of Apollo. Its final remains were demolished in 1925. This church was made with blocks from the naiskos and other small buildings from outside the temple around 500 AD. After a serious earthquake in the 7th century AD, a reconstruction of the three-aisled basilica was erected. In the 11th century AD, another earthquake occurred and the church in the sekos collapsed. This was replaced by only a small chapel which was used for the Christian cult. Another early Christian church was constructed 100 meters north of the temple of Apollo, at approximately the same location where today the mosque stands. This church also employed the use of ancient blocks salvaged from the temple of Artemis nearby and the previously mentioned Doric stoa above. Its later history is not yet clear, but in 1830 their remains were used to erect a new church (dedicated to Saint Charalambos) for the recently arrived Greek settlers. In 1924 it was converted into a mosque for the Muslims just transported from North Greece during the Exchange of Populations. More chapels or churches surely existed in Byzantine Didyma because it was the seat of a bishopric, but about this age little is known. Some of these Byzantine churches either fell into disrepair or used as animal pens after the area was abandoned in the 16th century and reused by the newly settled Greeks at the end of the 18th century when the quarrying of the temple marble became a profitable trade.
