The tomb is named for the townsland in which it situated, Gaulstown, and sits at the foot of "Cnoc an Chaillighe" or "The Hill of the Hag".[3]
Features
The portal tomb most likely dates from around 3500 BC, and is considered one of the finest examples of portal tombs in the region,[2] and was first recorded by George Victor Du Noyer in 1864.[4] The tomb faces south east into the hillside, and consists of two east-facing portal stones which are 2.4 metres (7 ft 10 in) high, with a door stone between and a chamber consisting of three other upright stones. All of these support a rectangular capstone, which is 4.2 metres (14 ft) in length, and 1 metre (3 ft 3 in) deep. The tomb has been undergone maintenance in the past, with a concrete support added inside the chamber. There is evidence that some of the upright stones may have moved over time, as the shape of the chamber has been impacted.[3] It is likely that the structure was once enclosed by a mound or cairn, which has since been removed or eroded away.[5]
