AS part of the Heritage Open Days, the Music Room or theatre' at Ashwick House near Dulverton will be open offering a chance to find out about the building and its benefactor.

The music room is a remarkable, rustic building provided by Frank Green as a theatre or recreation hall for his staff and relatives in the 1920s.

Frank Green was an eccentric bachelor and wealthy industrialist who bequeathed the Treasurer's House in York to the National Trust. He moved to Exmoor in 1930 and died in 1954 at the age of 93.

The wooden music room is built on stone columns and is roofed with Roman style tiles. Within, formerly decorating the wings of the theatre, are paintings of theatre boxes; including one of King Edward VII and Queen Alexandra.

For Heritage Open Day the theatre will be open and the Exmoor Pony Centre, immediately opposite, will also be open and there will be a chance to find out more about the Exmoor Pony, its history, handling and grooming.

Jessica Turner, archaeological conservation advisor with Exmoor National Park Authority said: "The music room is not normally open to the public so this is a great opportunity to see this interesting building, learn more about its history and combine it with a visit to see Exmoor's most historic four-legged residents."
