The dominant building in the complex is the Temple of Hathor. The temple has been modified on the same site starting as far back as the Middle Kingdom, and continuing right up until the time of the Roman emperor Trajan. The existing structure began construction in the late Ptolemaic period at the time of Ptolemy Auletes in July 54 BCE and the hypostyle hall was built in the Roman period under Tiberius. In Egypt, Trajan was quite active in constructing buildings and decorating them. He appears, together with Domitian, in offering scenes on the propylon of the Temple of Hathor.
