Seti's well preserved tomb (KV17) was found in 1817 by Giovanni Battista Belzoni, in the Valley of the Kings; it proved to be the longest at 446 feet (136 meters) and deepest of all the New Kingdom royal tombs. It was also the first tomb to feature decorations (including the "Book of the Heavenly Cow") on every passageway and chamber with highly refined bas-reliefs and colorful paintings – fragments of which, including a large column depicting Seti I with the goddess Hathor, can be seen in the National Archaeological Museum, Florence. This decorative style set a precedent which was followed in full or in part in the tombs of later New Kingdom kings. Seti's mummy itself was discovered by Émil Brugsch on June 6, 1881 in the mummy cache (tomb DB320) at Deir el-Bahri, and has since been kept at the Egyptian Museum in Cairo.
