 The interior of the building, which has yet to be restored, consisted of a single rectangular room measuring 17x11 m, with a central apse framed by a large arch at the far wall.The apse contained a podium for a statue, now lost, that likely depicted Celsus, although some scholars have suggested it was Minerva, goddess of wisdom.A crypt containing Celsus's sarcophagus was located beneath the floor of the apse.
