[1] The building now known as Amroth Castle was a feudal residence in the early medieval period and was noted by Fenton (in 1810) as being in the hands of John Elliott of Eareweare (the local name for the estate) in 1690 who paid tax on five hearths.

[1] After passing through several hands, including the families of Biddulph and Bevan, the property was used by Dr John Howard Norton from 1851 to 1856 as a private lunatic asylum.

[3] It was in the hands of the Fussell family in 1861, and purchased in 1898 by shipping magnate Owen Colby Philipps, who later bought the White Star Line, and was created Baron Kylsant of Carmarthen and Amroth in 1923.

They moved out in 1930 when George inherited the Coventry title and estates[citation needed], and the building became a farmhouse.

[6] It was purchased in 1969 and converted into holiday accommodation, with a caravan park in the grounds, and as of 2025[update] National Historic Assets of Wales reports that it continues in this use with the same owner.
