Knowth

The main mound of Knowth, whose ancient name is Cnogba, is a beautiful sidhe (faerie) mound orbited by several satellite mounds. Knowth is said to be the burial place of Bua, daughter of Ruadri Ruad. Its east-west-facing entrances as well as petroglyphs on rocks surrounding the main mound describe complex cycles of our solar system. Knowth has several smaller satellite mounds such as this one.
