The Province where Puerto Natales is located received the name �ltima Esperanza (Last Hope) from the sailor Juan Ladrilleros, who was seeking the Strait of Magellan in the year 1557. It was his "last hope" to find the Strait after exploring the maze of channels between the waters of the Pacific and the mainland. It was not until three centuries later, in 1830, that another major expedition sailed through the fjords and channels of �ltima Esperanza. This was the British expedition of the sloop HMS Beagle. Some of the expedition - (Robert FitzRoy, William Skyring and James Kirke) and their senior officers - are remembered by several place-names in the area. Commander Fitzroy was the captain during the Second voyage of HMS Beagle (1831�1836).
In 1870, interest in the region of Ultima Esperanza was rekindled. Among the daring travelers who ventured these desolated lands, was Santiago Zamora, also known as 'Baqueano' Zamora. He discovered the lake district of the Torres del Paine area and many wild horses locally known as 'baguales'. Another was the English traveller and writer Lady Florence Dixie, commemorated in the city's present-day Hotel Lady Florence Dixie. Dixie authored the book, Across Patagonia.
Puerto Natales was founded on May, 1911 as a port for the sheep industry. During the last half of the 20th century the sheep industry declined and many people from Puerto Natales started to work in the coal mines of R�o Turbio in Argentina. During the zenith of the sheep industry in Patagonia, two large "frigorificos" or freezer plants, were constructed in the Natales area, of which one has survived.The plant at Puerto Bories, about 4 km NW from Puerto Natales, was a project of the Sociedad Explotadora de Tierra del Fuego. The Puerto Bories site was inaugurated in 1913 and pwas in production until 1993. The Cold-Storage Plant was constructed in "Post Victorian Industrial" architectural style and features of number of British machinery examples which
