Ed Dakka Temple

Ad-Dakka was a place in Lower Nubia. It is the site of the Greco-Roman Temple of Dakka, dedicated to Thoth, the god of wisdom in the ancient Egyptian pantheon. The temple was initially a small one-room shrine or chapel, first begun in the 3rd century BC by a Meroitic king named Arqamani in collaboration with Ptolemy IV who added an antechamber and a gate structure. Ptolemy IX "subsequently enlarged the temple by adding a pronaos with two rows of probably three columns." During the Roman period, the Emperors Augustus and Tiberius further enlarged the structure with "the addition, at the rear, of a second sanctuary as well as inner and outer enclosure walls with a large pylon. The sanctuary contained a granite naos." The Temple of Dakka was transformed into a temple fortress by the Romans and surrounded by a stone wall, 270 by 444 metres long, with an entrance along the Nile.
