Knowth is a mound being excavated and in Ireland (53o 43' latitude North, 6o 30' W longitude and 60 m high). It is more than 5000 years old (build around 3100 CalBC or 2540 bc), and thus older than the pyramids in Egypt! This building, which is a big mound of some 84 meters in diameter, stands in the Boyne Valley, some 40 km north of Dublin. In this region two more big mounds are located: Dowth and Newgrange.
