It is known for its Romano-British remains. Gateholm is owned by the National Trust as part of their Marloes Sands and Mere estate.
Name
The name, recorded as Goteholme in 1480, derives from Old Norse for "goat island".
Geography
Gateholm is at the western end of Marloes Sands, and is accessible only at low tide. Gateholm rises to a small plateau 40 metres (131 feet) high, and with an area of about 4 ha. The island consists of steeply-dipping Old Red Sandstone. The rock strata date from the Prídolí Epoch of the Silurian; the exceptional exposure here and on the adjoining Albion Sands have resulted in the location's inclusion in the Geological Conservation Review as a candidate for protection as a geological site of special scientific interest (SSSI).

National Trust and statutory protection
Gateholm was bought by the National Trust in 1981 under Enterprise Neptune, a longterm project to acquire and maintain stretches of coastline to retain its character and preserve its wildlife. The National Trust had already been given over 450 acres on Marloes Peninsula, including Marloes Court Farm, donated in 1941, which included the Marloes Sands and Albion Sands coastline. This, along with adjacent donations of West Hook (1940), Runwayskiln Farm (1941) and Trehill Farm (1942), meant the Trust already owned much of the peninsula and its coast. The acquisition in 1981 of Gateholm plus the Martin's Haven deer park at the western headland, meant the entire coastline and peninsula could be managed under National Trust leases and access arrangements. The Gateholm coastline also lies within two European designated areas. The 'Pembrokeshire Marine' Special Area of Conservation is notable for its bays, reefs and grey seals, whilst the Special Protection Area for 'Skomer, Skokholm and the seas off Pembrokeshire', gives protection for the large breeding seabird populations.
Archaeology
The island contained around 130 roundhouses as well as huts of a rectangular shape. The rectangular houses were mostly arranged in rows end-on and surrounded by small courtyards. Excavations of some of these hut sites conducted in 1910 and 1930 found evidence for occupation in the Roman period, with finds including pottery, coins, and a small bronze stag. There was also a bronze pin of Irish origin and dating from the 6th century. One of the houses had a stone phallus buried upright in one of the main post holes. The houses were built of turf with stone facings, the roof being carried on a ridge-pole between the posts. The site has been interpreted variously as a native Romano-British settlement with later occupation, and as an early monastic complex.
Filming
Gateholm was the subject of an episode of the British archaeology television series, Time Team (Series 19, episode 01). The island featured prominently in the 2011 film Snow White and the Huntsman; a computer-generated castle was superimposed on the island post-production.
