The name is Welsh, and probably means "on (the brook called) Rhath".[4]
History
The beach stretches the whole length of the village and at extreme low tide, the petrified forest, destroyed when sea levels rose 7,000 years ago, can still be seen. Fossilised antlers, nuts and animal bones and Neolithicflints have been discovered.[5]
The parish, which appeared as Amrath on a 1578 parish map of Pembrokeshire,[6] was an important anthracitecoal mining area until the end of the 19th century. Slight remains of mines and tramways are still visible. Ruins of Amroth Castle still remain, and one mile inland is the Anglicanparish church of St Elidyr, which is a grade II* listed building.[7]
Amroth Castle stands on the north side of the unclassified coast road east of the village of Amroth. It is surrounded by a high wall with an entrance archway at the south-western corner. The present building is a 19th-century country house built in the style of a mock castle which possibly replaced a small stone castle dating from the 12th century. The gatehouse is much restored. The ruinous remains of the house are a grade I listed building.[8]
After passing through several hands the castle was used as a lunatic asylum in the 1850s. Converted back to a private house in the 1880s it was later owned and occupied by Owen Colby Philipps, the shipping magnate who bought the White Star Line and was created Baron Kylsant of Carmarthen and Amroth in 1923.[9] It passed to his daughter Nesta, who had married George Coventry, grandson of the 9th Earl of Coventry. They moved out in 1930 when George inherited the Coventry title and estates.
The beach which stretches the length of the village earned a Blue Flag award in 2020 and the eastern end has had a lifeguard for part of the summer.[15] Public toilets are available at either ends of the village.[16][17] The main car park is managed by Pembrokeshire Coast National Park Authority.[18]
