1743 – The Wonderful Barn, Leixlip, Co. Kildare

The Wonderful Barn is a corkscrew-shaped barn built on the Leixlip side of Castletown House Estate, which borders Leixlip and Celbridge, Ireland. Flanked by two smaller dovecote towers, it was built with the stairs ascending around the exterior of the building. The construction project likely served as a way to keep the local poor employed. In this it is not unlike the Conolly Folly (an Obelisk) which was built on the estate in 1740-41.
