The Temple of Esna conveys a sense of the importance which the Ancient Egyptians placed upon their places of worship. All Egyptians who entered the confines of an Egyptian temple were required "to comply with the strict rules regarding ritual purity." According to inscriptions carved on the walls of the Temple of Esna, those who entered this temple were expected to fastidiously cut their fingernails and toenails, remove other body hair, wash their hands with natron (a natural occurring salt), "be dressed in linen (they were forbidden from wearing wool), and not to have had sexual intercourse for several days.

 The Temple of Esna was the last Egyptian temple to be decorated with hieroglyphic texts. It was built during the Ptolemaic Period. The temple was then enlarged with a hypostyle hall, and decorated mainly in Roman times.
