History

It was built between 4000 and 3000 BC by some of the earliest farmers to inhabit the island. It is also known as Brownshill Portal Tomb, so-called because the entrance to the burial chamber was flanked by two large upright stones (orthostats) supporting the granite capstone, or roof, of the chamber. The capstone is thought to have been covered by an earthen mound and a gate stone blocked the entrance.

At Brownshill both portal stones and the gate-stone are still in situ; the capstone lies on top of the portals and gate-stone and slopes to the ground away from the entrance. Not much additional information is available on Brownshill because it has never been excavated.

The capstone at Brownshill, weighing an estimated 150 tonnes, is the largest discovered in Europe.
