The Abydos Temple is one of the most mysterious structures from ancient Egypt. However, a recent discovery by a team of archaeologists has shed some light on its secrets. The temple's main purpose was to serve as a funerary complex for Seti I and his family.

The Osirion or Osireon, meaning "Menmaatre beneficial to Osiris" sometimes called the Osiris Complex, is an ancient Egyptian temple. It is located to the rear of the temple of Seti I. It is an integral part of Seti I's funeral complex and is built to resemble an 18th Dynasty Valley of the Kings tomb.
