Groix (French pronunciation: [ɡʁwa]; Breton: Enez Groe) is an island and a commune in the Morbihan department of the region of Brittany in north-western France.

Geography#edit

Groix lies a few kilometres off the coast of Lorient. Several ferries a day run from Lorient to Groix.

There are a few small towns on the island. High cliffs are on its north coast and sandy beaches in secluded coves on the south coast. Groix is also home to a wide variety of sea birds. Groix is also famous for hosting the only convex beach in Europe, which also shifts with ocean currents. During the last 15 years, the beach has moved half a kilometer (546.807 yards) westbound.

Geology#edit

The geology of Groix is distinct from that of the nearby continent, and the east and south coasts have been designated a mineral nature reserve since 1982.[citation needed] More than 60 minerals can be found on the island, particularly blue glaucophane (observable on the surface), epidote or garnet.[citation needed] The island mainly consists of schist.[citation needed]

History#edit

A major naval battle between Britain and France took place off Groix in 1795.

The island is the major setting in the fourth book of The Enzo Files series—Freeze Frame—by author Peter May.
