Sham Castle is a folly on Claverton Down overlooking the city of Bath, Somerset, England.
[1] It was probably designed around 1755 by Sanderson Miller and built in 1762 by Richard James, master mason for Ralph Allen, "to improve the prospect" from Allen's town house in Bath.
Ralph Allen's nearby Prior Park Landscape Garden is home to the Sham Bridge.
[5] This structure is likewise a screen at the end of the Serpentine Lake which appears to be a bridge.
In Piltown, County Kilkenny, Ireland is a partially-built monument known as 'Sham Castle'.
