About 1km to the north of the Temple of Ramses II are the remains of the Temple of Dakka, begun by the Nubian pharaoh Arkamani (218–200 BC) using materials from much earlier structures and adapted by the Ptolemies and the Roman emperor Augustus. Originally situated 50km north of here, it is dedicated to the god of wisdom, Thoth, and is notable for its 12m-high pylon, which you can climb for great views of the lake and the surrounding temples.
