The temple that the Greeks called the Memnonium in Abydos, actually dedicated to Seti I, Osiris and Isis along with Ptah,Ptah-Sokar, Nefertem, Re-Horakhty, Amun, and Horus, is one of the major archaeological sites in that region. It was begun by Seti I and finished by his son, the great Ramesses II. In fact, this structure built of fine white limestone is actually one of the most impressive religious structures in Egypt.
The present facade of the Temple was once the backdrop to the second of the two courtyards, the first of which, along with its entrance pylon, have long since fallen into ruin.
The temple, in the shape of an L, once had a landing quay, a ramp, a front terrace, two pylons, though the outer one is mostly lost, with two courts and pillared porticoes, followed by two hypostyle halls and seven chapels, with additional chambers to the south making up the short leg of the L. Storage chambers fill the area from the southern wing to the front of the temple.The main body of the temple was symmetrical back to the seven chapels. While the L shaped floor plan of this temple is unusual, analysis seems to show that the southern wing was no afterthought, but the result of a well thought out alternative to the usual axial temple plan.
