Bryher is part of which island group off the coast of the United Kingdom?

Bryher is one of the smaller of the inhabited islands of the Isles of Scilly, with a population of 84 in 2011, spread across 134 hectares (1.34 km2).

The Isles of Scilly is an archipelago off the southwestern tip of Cornwall, England. One of the islands, St Agnes, is the most southerly point in Britain, being over four miles (six kilometres) farther south than the most southerly point of the British mainland at Lizard Point, Cornwall.

The island is a procession of prominent hills all joined to one another by low-lying necks and sandy bars. It would only need sea levels to rise by a few metres for the southern part of Bryher to transform itself into a group of five or six separate islands. As all these hills – Gweal, Timmy's, Watch, Heathy and Samson – are too exposed and windswept to be cultivated and Bryher's ninety residents have to make their lives in a relatively narrow zone between hill and shore.

The infamous Hell Bay is on the north-west coast of Bryher, immediately to the south of Shipman Head. This Atlantic-facing cove became a notorious place for shipwrecks in the 18th and 19th centuries, although most ships wrecked on Scilly were wrecked before they could reach Hell Bay.
