Danyrallt Park was built as a villa in the 1840's, replacing the 'Old Tanyrallt' (Nprn 17288). In 1864-5, the villa and an adjacent farmhouse were joined and named 'Dirleton'. The building is thought to have had a stone circular staircase in a canted bay. In 1881, the building was renamed Danyrallt Park. It was burned down in the 1940's.
