Chilean colonization of the Strait of Magellan

The Chilean colonization of the Strait of Magellan began in 1843 when an expedition founded Fuerte Bulnes. In 1848 the settlement of Punta Arenas was established further north in the strait and grew eventually to become the main settlement in the strait, a position it holds to this day.
