The site was excavated during the First World War by Clarence Stanley Fisher. Excavations began in the anterior part, which is formed by a large courtyard of approximately 15 sq metres, opening on the south by a large door with reliefs supplying the names of the king and the epithets of Ptah. Only this part of the temple has been unearthed; the remainder of the chamber has yet to be explored a little farther north. During the excavations, archaeologists unearthed the first traces of an edifice built of mudbrick, which quickly proved to be a large ceremonial palace built alongside the temple proper. Some of the key elements of the stone temple were donated by Egypt to the museum at the University of Pennsylvania, which financed the expedition, while the other remained at the Egyptian Museum in Cairo.
