Steep Holm (Welsh: Ynys Rhonech, Old English: Ronech and later Steopanreolice[1]) is an English island lying in the Bristol Channel. The island covers 48.87 acres (19.78 ha) at high tide, expanding to 63.26 acres (25.60 ha) at mean low water.[2] At its highest point it is 78 metres (256 ft) above mean sea level. Administratively it forms part of the unitary authority of North Somerset within the ceremonial county of Somerset;[3] between 1 April 1974 and 1 April 1996, it was administered as part of Avon.[2] Nearby is Flat Holm island (Welsh: Ynys Echni), part of Wales.

The Carboniferous Limestone island rises to about 200 feet (61 m) and serves as a wind and wave break, sheltering the upper reaches of the Bristol Channel. The island is now uninhabited, with the exception of the wardens. It is protected as a nature reserve and Site of Special Scientific Interest (SSSI) with a large bird population and plants including wild peonies. There was a signal station or watchtower on the island in Roman times, but there may have been human habitation as early as the Iron Age. In the 6th century it was home to St Gildas and to a small Augustinian priory in the 12th and 13th centuries. An inn was built in 1832 and used for holidays in the 19th century. A bird sanctuary was established in 1931 and since 1951 has been leased to charitable trusts. It is now owned by the Kenneth Allsop Memorial Trust.

In the 1860s the island was fortified with ten 7-inch rifled muzzle loaders as one of the Palmerston Forts for the coastal defence of the Bristol Channel until it was abandoned in 1898. The infrastructure was reused in World War I and II when Mark VII 6-inch breech-loading guns and search lights were installed. To enable the movement of materials, soldiers from the Indian Army Service Corps initially used mules and then installed a cable-operated winched switchback railway.
