The island is more commonly known as "La grande galette" (The Big Biscuit) due to its round shape and almost flat surface (its highest peak, the Morne Constant Hill, rises to 204 m). Formerly having over 106 sugar mills, it is also called "The Island of a Hundred Windmills", or the "La Grande Dependence", being the biggest dependency of Guadeloupe. The island is undulating substrate calcareous, cooled by the trade winds and subject to cyclones and earthquakes.
