Powderham Castle is a fortified manor house and a Grade I listed building. The park and gardens are Grade II* listed in the National Register of Historic Parks and Gardens. The castle was expanded and altered extensively in the 18th and 19th centuries, most notably by James Wyatt in the 1790s. The castle remains the seat of the Courtenay family, Earls of Devon.

 

The castle is reputedly haunted by the ghosts of a woman and baby that were bricked up alive. Renovation work in the 19th century apparently uncovered their remains. Alos said to wander the castle and grounds is the Grey Lady, whom some have suggested is Lady Frances. She was married to Viscount Courtenay in 1741. However, her apparition is said to be a death omen, heralding the death of the head of the Courtenay family.
