Shambellie House is a Scots Baronial style mansion set within the 2,000 acre Shambellie Estate in the town of New Abbey, Dumfries & Galloway. Built by William Stewart in 1858, the family lived at Shambellie until 1977, when William's great grandson Charles gave the house to the Scottish nation. It subsequently opened as the Shambellie House Costume Museum in 1982, becoming the National Museum of Costume. The Museum closed in 2013, and the Prince's Regeneration Trust are now working with the local community to re-use the building for community use.
