Antrim Castle was erected in stages between 1613 and 1662. It was destroyed by fire in 1922 and finally demolished in the 1970s. All that remain are a slightly raised grassed platform as well as a freestanding Italian stair tower which was built in 1887 and a gatehouse, which was built around 1818 with twin neo-Tudor towers, with older connecting walls.
The gardens, originally dating from the 17th-century, are a popular tourist attraction. Jacobean-Revival outbuildings of coursed rubble basalt with sandstone dressings were built about 1840. The entrance gateway to the demesne has octagonal turrets. The stable block was later converted for use as a family residence and renamed Clotworthy House. This was acquired by Antrim Borough Council and converted for use as an Arts Centre in 1992.
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).
