Den was interred within a tomb ("Tomb T") in the Umm El Qa'ab area of Abydos, which is associated with other First Dynasty kings. Tomb T is among the largest and most finely-built of the tombs in this area, and is the first to feature a staircase and a floor made of granite.
His was the first tomb to have a flight of stairs leading to it, those of earlier kings being filled directly above from their roofs. Tomb T is also the first tomb to include architectural elements made of stone rather than mud-brick. In the original layout for the tomb, a wooden door was located about halfway up the staircase, and a portcullis (boulder) placed in front of the burial chamber, designed to keep out tomb robbers. The floor of the tomb was paved in red and black granite from Aswan, the first architectural use of such hard stone on a large scale.
Twenty labels made of ivory and ebony were found in his tomb, 18 by Flinders Petrie in the spoil heaps left by the less thorough Émile Amélineau. Among these labels are the earliest known depictions of a pharaoh wearing the double-crown of Egypt, as well as running between ritual stele as part of the Sed festival. Also found are seal impressions that provide the earliest confirmed king list.
Tomb T is surrounded by the burial sites of 136 men and women who were buried at the same time as the king. Thought to be the king's retainers, an examination of some of the skeletons suggests they were strangled, making this an example of human sacrifice which is considered to be common with the pharaohs of the First Dynasty. This practice seems to have ceased by the end of the dynasty, with ushabtis taking the place of the bodies of actual people to aid the pharaohs with the work expected of them in the afterlife. [X]
