Montacute House is a late Elizabethan mansion with garden in Montacute, South Somerset.
All parts are maintained by the National Trust. Its Long Gallery, the longest in England serves as a South-West outpost of the National Portrait Gallery displaying a skilful and well-studied range of old oils and watercolours.
A textbook example of English architecture during a period that was moving from the medieval Gothic to the Renaissance Classical, and one of few fine houses to survive almost unchanged from the Elizabethan era, the house has been designated byEnglish Heritage as a Grade l listed building, and Scheduled Ancient Monument. It was visited by 125,442 people in 2013. Designed by an unknown architect, possibly the mason William Arnold, the three-storey mansion, constructed of the local Ham Hillstone, was built in about 1598 by Sir Edward Phelips, Master of the Rolls and the prosecutor during the trial of the Gunpowder Plotters.
The house and its gardens have been a filming location for several films and a setting for television costume dramas and literary adaptations.
