Wilton House near Salisbury in Wiltshire has won the Historic Houses Association's (HHA) Restoration Award for 2010.

The award, in conjunction with art auction house Sotheby's and now in its third year, is for Wilton's work on its private dining room. The project is the centrepiece of a range of restoration schemes at the house, which has also seen its library, north ante library, smoking rooms, cloisters, gothic hall, inner courtyard and north forecourt returned to their former glory. Wilton House stands on the site of a 9th century nunnery founded by King Alfred. This was replaced by a 12th century Benedictine abbey which was surrendered at the time of the Dissolution of the monasteries to King Henry VIII, who gave it and the surrounding land to William Herbert around 1542.

Wilton House has remained in the Herbert family since then and is the home of the Earl of Pembroke. The 460 year old house - with its history, architecture, art treasures and 21 acres of gardens and parkland - today attracts visitors from all over the world. Three commendations were also announced by the HHA and Sotheby's - Ballywalter Park in Newtownards, Northern Ireland; Thorpe Hall in Wycliffe, Co. Durham; and The Stables at Penpont in Brecon, Wales.

The previous winners of the award were Markenfield Hall in Yorkshire and Chillington Hall in Staffordshire.
