I don't have a picture of Site 10, so here is Martin Brennan's illustration of the west side of the mound; Site 10 would be behind the standing stones and Sites 9 & 10 at the right of the picture.

Knowth - Site 10

Site 10 was discovered during excavations in 1972. The site was very badly damaged when a ditch and drain were dug across the mound, no trace of which remains. There are 2 kerbstones and the remains of a chamber. Eogan considered that the internal structure was undifferentiated and probably oriented to the southeast.
