In architecture, flushwork is decorative masonry work which combines on the same flat plane flint and ashlar stone. If the stone projects from a flat flint wall then the term is proudwork, as the stone stands "proud" rather than being "flush" with the wall.

Butley Priory, sometimes called Butley Abbey, was a religious house of Canons regular in Butley, Suffolk, dedicated to The Blessed Virgin Mary. It was founded in 1171 by Ranulf de Glanville, Chief Justiciar to King Henry II (1180-1189), and was the sister foundation to Ranulf's house of White canons (Premonstratensians) at Leiston Abbey, a few miles to the north, founded c. 1183. Butley Priory was suppressed in 1538.
