Auchagallon Stone Circle is the remains of a Neolithic or Bronze Age burial cairn, surrounded by a circle of fifteen stones. The cairn and stone circle is situated on a slight ledge of a west-facing slope, overlooking Machrie Bay. The circle comprises fifteen blocks varying in height from 0.5 metres to 2.3 metres. The stones are of red sandstone, except two which are a pale grey granite. The circle has a maximum diameter of 14.5 metres.
In the centre is a large stone cairn. Antiquarians digging here in the 19th century found a burial cist in the centre, although there are no records of any other remains. Although the monument is now called a stone circle, it was probably built as a kerbed cairn.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
