Renowned for hosting a population of Lesser Antillean iguanas (Iguana delicatissima), a protected species endemic to the Caribbean, and for serving as a refuge for large migratory and sea birds as well as bats, Chancel islet is the largest islet in Martinique with an area of approximately 198 acres (80 ha). The islet - which bears the name of Monsieur de Lagrange-Chancel, its purchaser in 1891 after the passage of a destructive and deadly cyclone - is one of the ten islets of Le Robert on the Atlantic coast of the island. With a maximum altitude of 223 ft (68 m), it offers swimming enthusiasts the white bottoms of the Trapèze beach that borders it. Chancel islet's human occupation dates back to the Caribs times, as evidenced by the remains of a lime kiln, a pottery workshop, and a dungeon.
