In 1957 Tom's eldest son Captain Michael Tom Baillie Grohman sold the castle to Ernest Kump, an American architect of Austrian ancestry. Captain Baillie Grohman also sold off some the castle's valuable antiques, mostly to Swiss dealers. Mr Kump undertook extensive works to repair the castle walls and fabric and installed oil central heating. His restoration work uncovered further gothic wall paintings in 1968. He subsequently left it to his nephew Christopher Kump who opened the castle to paying guests.
