This Chambered Tomb is one of the least visited sites of the Boyne Valley Complex infact, many aren't even aware of it being part of the complex because of it's distance from the main sites. At first glances it does not appear to be very interesting; from the outside! But inside it is unique.

What make the Tomb unusual is it's internal size (see Above). It is at least 30 ft across in diameter forming a perfect circle. It still has the cross structure formed by the entrance and three burial portals, and is similar in this respect to the other structures found around Western Europe. It is believed to have been built during the same period as NewGrange, but the roof collapsed due to weight very shortly,1000 years or so after it was build due to it's unique structure.

All the Portals have the same designs as NewGrange and Knowth, the Spirals of the rear walls, and the Lozenge/Zig patterns on the Lintels above each.
