The Kiosk of Qertassi is "a tiny Roman kiosk with four slender papyrus columns inside, and two Hathor columns at the entrance. It is a small but elegant structure that is unfinished and not inscribed with the name of the architect, but is probably contemporary with Trajan's Kiosk at Philae. According to Günther Roeder - the first scholar to publish research on this building -the kiosk of Qertassi dates to the Augustan or early Roman period. The structure "is only twenty-five feet square, and consists of a single Hathor court that was originally surrounded by fourteen columns connected by screen walls. Of the 14 pillars, only 6 have survived in place. The pillars or columns were made of brown sandstone; the structure itself was perhaps connected to a small temple on the East Bank of the Nile, which was still in existence in 1813.

This charming kiosk that stands now at the site of New Kalabsha south to the High Dam, stood originally before the entrance to the sandstone quarries of Qertassi. Its capitals "are decorated with Hathor heads, in honor of the goddess who was the patron of quarry-men and miners. Since Hathor was often associated with Isis, as she is at Philae, it has been suggested that this kiosk and the small temples of Dabod and Dendur were way stations on the processional route taken by priests bearing the image of Isis around Lower Nubia, which was considered to be her estate.
