Broch of Ayre, also known as St. Mary's Broch, is an Iron Age structure in Orkney. It was first excavated in December 1901 and then again in the summer of 1909. Little now survives, though part of the broch wall is still extant. The excavations revealed traces of internal architecture and external, probably later, structures.
The 1901 excavations revealed that the broch wall survived to over a metre in height in parts, with an entrance passage facing to the south-east. The passage contained a broken lintel and architectural features including a guard cell. The interior of the broch contained radial partitions using vertical slabs of stone, and a lintelled well. The broch itself was almost eighteen metres in external diameter, with walls almost five metres thick in places. The 1909 excavation revealed external buildings, likely built later, and the interior of the broch may also have been re-used and partially remodelled in a subsequent phase.
A number of iron objects were discovered, including two spearheads and an axehead. Locational information from the excavation is poor, although one of the spearheads was found associated with the guard cell. Nail heads, bronxe pins and a bronze ring were also found. Evidence of metal-working, including a mass of conglomerate with fused pottery and iron, was also found. Bone pins, combs, antler fragments and cetacean bone vessels were found along with several dice. A large quantity of pottery was also found, along with the remains of whale, seal, ox, pig, red deer, sheep, horse, gannet and other birds, and human bone.
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).
