Knowth - Site 12 Site 12 is located on the northwest side of the great mound. Six kerbstones were found on the old ground surface in their original position, and five more turned up during the excavation. Site 12 is about 15 meters in diameter. The undifferentiated passage and chamber are 7 meters long, with a sillstone marking off the end of the passage; the chamber is 2.5 meters long. The chamber was surrounded by an oval stone cairn about 50 cm high. Cremated remains and some bone pins were found in the chamber; 6 pieces of flint were found in the mound. There is an engraving on 1 of the kerbstones. Site 12 restored in 2002. Site 12 is oriented to the southeast, quite possibly to the rising position of the midsummer lunar extreme, which would occur every 18.6 years.
