The two main points of interest in Esna are its lively tourist-oriented market, which fills a couple of streets leading inland from the corniche. The other is the temple of Esna. The temple, which has only been partially excavated, is about 200 meters from the river and some 9 meters below street level.
The temple dates back to the Ptolemaic and Roman Period and one of the last temples built in Egypt, stands today in its excavation pit, 9m below the modern ground level. It was dedicated to the god Khnum and several other deities, including Neith, Heka, Satet and Menheyet. The remains of the Temple contain a hall of columns, with 24 pillars, beautifully decorated with lotus and palm capitals.
The walls are covered with 4 rows of relief's, showing Ptolemaic and Roman Emperors dressed in Pharaoh Costumes, sacrificing to the God of the Temple. On both sides of the Temple entrance there are chambers that were used by the priests and keepers of the Temple as storerooms.
