Knowth 15 Site 15 is the largest satellite at Knowth, measuring about 23 meters in diameter which is as large as the cairns at Carrowkeel and Loughcrew, and the majority of the Carrowmore circles. The monument is located to the north-east of amd about 10 meters from the kerb of the great mound. The mound survived to almost a meter high; 26 kerbstones were found, 19 of which were in their original positions; this is probably about half of the original total of kerbs. The kerbstones were completely removed from the west and north side of the mound. The site was much disturbed during the Bronze Age when burials were inserted into the mound, and later during the Christian era when souterrains were built through the site. The portion of the kerb facing the great mound is flat. An early illustration of a stone urn or basin which was found at Knowth; the artwork is very similar to the great cauldron/basin in Knowth East. The whereabouts of this interesting artifact are unknown. There is a bottle-shaped undifferentiated passage and chamber which measures just over 9 meters in length, and is divided by 3 sillstones. Most of the passage and chamber stones were found in their original positions, but there were no capstones or corbells present. Many of the stones from the smaller mounds at Knowth were reused for roofing the souterrains in the early Christian period. The cremated remains of two or three people were found within the chamber. Also found were some bone beads, shards of pottery which included Carrowkeel ware, and 26 pieces of flint. Three of these were worked, the rest were waste pieces. Art was found on three of the interior stones, one of which is a sillstone, and two of the kerbs. The orientation is to the southwest, and seems to be aligned to the winter solstice sunset; the mound may be a smaller and earlier version of Dowth South.
