Brunswick Peninsula

The Brunswick Peninsula is triangular in shape, joined to the mainland in the north by a 16 kilometres (9.9 mi) wide isthmus.

It measures 115 kilometres (71 mi) in length from the base to Cape Froward, the southernmost point of the American mainland.

In his honor, English explorers gave the name Brunswick to the newly charted land of South America.

The area is thinly populated with all settlements clustered on the east coast but the entire peninsula is treated as a single administrative unit, the commune (municipality) of Punta Arenas.

The commune also includes all islands west of the Isla Grande de Tierra del Fuego and north of Cockburn and Magdalena channels.
