Panoramic view of interior of Temple of Seti I, Abydo (click on the picture to enlarge it.)
Pictured above is the Second Hypostyle Hall, built by Seti I. The entry way on the right opens into the First Hypostyle Hall, which was built by Seti's son Ramses II after his father's death. The lighted room on the far left is the Sanctuary of Seti I. It is one of the seven separate chapels/sanctuaries that line the entire length of the left wall. Each sanctuary is dedicated to one of the following dieties: Horus, Isis, Osiris, Amun-Re, Re-Harakhiti, Ptah, and Seti I.
Looking at this picture always immediately put me back inside the temple itself.
