Ramesses II built the fabulous mortuary temple on the site of Seti I's ruined temple. This great temple reportedly rivaled the wonders of the temple at Abu Simbel. However, Ramesses built the temple too close to the Nile and the flood waters took their toll. Only a single colonnade remains of the First Courtyard. In front of the ruins is the base of the colossus of Ramesses that once stood 17m high. The statue would have weighed more than 1,000 tons. The statue fell into the Second Court and the head and torso remain there, but the other broken pieces are in museums all over the world. The ceiling in the Astronomical Room is still intact with the illustration of the oldest known 12 month calendar.
