1756 – Glenarm Castle, Co. Antrim

Architect: Christopher Myers / William Vitruvius Morrison



There has been a castle at Glenarm since the 13th century, and it is at the heart of one of Northern Ireland’s oldest estates. The present castle dates largely from 1756 although work has been carried out by most generations of the Antrim family.

In 1750 the fifth Earl of Antrim moved to Glenarm, a Jacobean mansion from around 1636. Christopher Myers, an English engineer, was employed on renovating the castle. Myers transformed the ruin into a Palladian mansion. The main front had an eccentric appearance, for its entire fenestration consisted of three-light Venetian windows, with curved colonnades ending in pavilions with pyramid shaped roofs on either side.


“Anne Catherine McDonnell, Countess of Antrim in her own right, wanted a fashionably romantic seat, and her architects were the Irish brothers William and John Morrison. Their plans, exhibited at the Royal Academy in 1824, were not very original, for they had already ‘Jacobethanised’ Miltown House in Kerry with almost identical towers, crenellations, side wing and porch to Glenarm. The ‘Barbican’ gateway was also based on one at another house. This gateway, the revamped servants’ wing and four comer turrets were quickly built, but then money ran out, and the castle kept much of its Palladian features until the 1850s, when the ‘Wee Earl’, Anne Catherine’s nephew, completed the Morrisons’ plans”.
