Originally known as Llan y llan, the house was built in 1856 for Henry Crawshay, the ironmaster of Cinderford in the Forest of Dean. Crayshaw died in 1879. The house later became the Langland Castle Hotel, it was enlarged by John Norton of London in a similar style. The South Wales Daily Post of the 31st October 1896 referred to the installation of an oil gas plant at the Langland Bay Hotel by the Incandescent Company in 1895. Later the hotel was owned by Evan Walters of Llandrindod Wells, but in 1922 it became a convalescent home. A gasometer was marked on the 1898 OS map, above the beach, indicating a private gasworks to the hotel. It was not marked on later maps.
