It is believed that the Roman tomb located behind the school of the Companions belongs to the early Roman period of the second or third century. It was built with black stone in the form of a rectangle. It forms the lower floor of a 12th-century Seljuk mausoleum, the upper floor of which was demolished. The tomb was discovered and restored in 1956, and there are tombstones from the period between 1317 and 1318 in this tomb.
