A STUNNING barn conversion which once formed part of a 12th century castle is on the market for £2.5 million.

The Grade II listed six-bed home, which was one a pig sty, sits in the shadow of Amberley Castle, which dates back to 683AD.

The barn was once lived in by the bishops of Chichester and is believed to date back to the 17th century.

Today it is just next door to the castle, which is now run as a hotel and wedding venue.

About 16 years ago the barn was converted by the current owner, who is believed to have designed it himself.

The property had previously been on the market in 2016 for £3.75 million but offers failed to come in for unique home, forcing the owner to drop the asking price.

The accommodation spreads over 9,000sqft and also includes two single-bed cottages on the grounds.

The property has stunning views of the South Downs National Park.

The main barn consists of six bedrooms, six bathrooms and four reception rooms that include a grand dining hall, a spacious sitting room and a kitchen-breakfast room.

Outside there is a large timber framed double car barn, a garage and store room.

Adjacent to the neighbouring castle are two converted cart cottages each with a sitting room, a bathroom and a double bedroom.

There are landscaped grounds with large lawns, patio areas for seating and a feature walled garden.

The property is on the market with estate agents Jackson-Stops.
