Santa Rosalía is a city located on the Baja California peninsula, in the northern part of the Mexican state of Baja California Sur. It was named after Saint Rosalia, although the reason for the name is not quite clear since the Misión de Santa Rosalía is not located by the town, but rather in Mulegé, about 100 km (62 mi) south, and the local parish is devoted to Santa Bárbara. (See: Spanish missions in California.)

Santa Rosalía is a port city, and a regular ferry connects with Guaymas, Sonora, on the other side of the Gulf of California. At the Palo Verde Airport daily flights are available from Guaymas and twice a week from Hermosillo, Sonora.

This town boasts French influence, particularly in its architecture. The French company El Boleo founded the town in 1884 and exploited copper mines there until they closed in 1954. They built houses and installed a metallic church building (The Santa Barbara parish) which is argued to have been designed by Gustave Eiffel.

Unlike many other mining sites, the industrial facilities which are located in the very middle of the town, were never dismantled. Of particular interest are the reverberatory furnace and the metallurgical converter, although they are currently not accessible by the public due to safety concerns. Old locomotives, mining equipment and machinery are visible everywhere. The main mining company offices (La dirección) have been converted into an industrial museum.

The 2010 census showed a population of 11,765 persons. The city is the seat of the municipality of Mulegé.

[edit] Boleo Copper Mine

Boleite (dark blue) and atacamite (blue-green) in clay, a high-grade ore specimen from Boleo.

The Boleo Mine is an unusual sediment-hosted copper-cobalt-zinc-manganese ore deposit. Seven large manto ore deposits have been identified.^[1]

A state owned company (CMSRSA) reopened the works using basically the same (rather archaic) process until the 1980s, when it was closed due to the low-grade of the ore with regard to the technology used.

Baja Mining, a Canadian firm, has been intermittently exploring and attempting to reopen the Boleo Mine since 2004. Baja Mining estimates their property contains a resource of 534 million tons of ore, containing 0.59% Cu, 0.051% Co, and 0.63% Zn. Baja also hopes to produce byproduct manganese.^[1] The project is active as of early 2010.^[2]

[edit] Facts and controversy on the metal church

One of the main attractions at the town is undoubtedly the metal church. Originally built entirely of stamped steel sheet squares, it is supported by a formidable steel structure in a sober and austere style. It has been brutally modified in favor of functionality (its former lateral corridors were turned into habitable space using crude masonry), and stripped of several of its original stained glasses. Despite these modifications, it still preserves some of the original 1800s spirit.

Tradition credited its design to architect Gustave Eiffel and that it was shown in the 1889 Universal Exposition of Paris, France, along with the tower, and that it was awarded a prize. Originally destined for construction in Africa, the French company director Charles La Forgue found it disassembled in Belgium and bought it in 1894, probably to alleviate the nostalgia of the French community who missed the lifestyle and glamour of the European architecture. In the early 1990s Angela Gardner, an American architectural student who visited Santa Rosalía and examined the church, came to a hypothesis that the church design was from a different architect, belonging to the House of Duclo rather than Eiffel's firm, to the dismay of the locals, who believe this would diminish the appreciation of the building. As no historical record or blueprint has appeared, neither version could be confirmed. The recent disclosure of the historical archives to the public by the INAH (Mexico's National Institute of Antropology and History) has not provided additional information.
