Trajan's Kiosk is a hypaethral temple located on Agilkia Island in Old Aswan Dam reservoir, southern Egypt. One of the largest Ancient Egyptian monuments standing today, it is conventionally attributed to the Roman emperor Trajan,[1] who gave it its current decorations, though some experts think the structure itself may be older, possibly dating to the time of Augustus.[2][3] The edifice was originally built on the island of Philae, near the lower Aswan Dam, and served as the main entrance from the river Nile[4].
