Osireion
Monument at Abydos · also called Osirion, Cenotaph of Seti I, Tomb of Osiris
The Osireion is a sunken symbolic tomb of Osiris behind Seti I's temple at Abydos. Its plain granite hall is famous, but its writing is in the corridors and end chamber: royal underworld books and a sky ceiling.
The Osireion was built for Seti I (c. 1290–1279 BC) as a cenotaph, a tomb without a body, linking the king with Osiris. Its central hall of huge red granite pillars stands on an island surrounded by groundwater, an image of the mound that rose from the first waters. Its plain, massive style has led some to claim it is far older, but the evidence ties it to Seti's reign.
The texts were carved partly under Seti and partly under his grandson Merneptah. They are the same underworld and sky books painted in the royal tombs of the Valley of the Kings, here cut in stone for Osiris: guides to the sun's night journey, its dangers and its rebirth at dawn.
What to see and read

A long passage carved with the Book of Gates, added under Merneptah. Most visitors cannot enter it.

Signs to look for
- Djed pillar R11ḏd The djed pillar, Osiris's backbone, is the key sign of the god this building honours.
- Sky N1pt The sky sign belongs to Nut, whose body forms the ceiling of the end chamber.
- Star N14sbꜣ The star fills the astronomical ceiling and writes the hours of the night.
Reading the hieroglyphs here
- Most of the time you see the Osireion only from the rim; bring a zoom lens for the pillars.
- Water levels change and parts may be flooded or closed; ask at the Seti I temple if it is open when you visit.
Point your camera at a wall Hiero Lens boxes the signs and names them, on your phone; nothing is uploaded. On worn stone, trace a sign over the photo.
