The building that lodges “Fuerte de San Diego” Acapulco Museum of History, in Guerrero, underwent a major maintenance program and a museographic restructuring in 4 of its halls, carried out by the National Institute of Anthropology and History (INAH) with the support of the civil association Adopte una Obra de Arte (Adopt an artwork).


New humidity control equipment was installed in Introduction and Navigation halls to counteract affectations to walls and roofs, after studies were conducted to determine the origin of the problem, informed Victor Hugo Jasso, director of the museum.

Because of its nearness to the sea, walls of Fuerte San Diego receive a great amount of humidity, which is absorbed constantly and penetrates several inches. This corrosion is the main affectation that ancient buildings suffer, so maintaining the good conservation state of the only historical monument of Acapulco, Guerrero, has become a constant and highly specialized task.

Architect Javier Najera Franco, coordinator of major maintenance work, explained that water saturation was measured with very precise devices on walls and roofs, where high levels of humidity were detected, in spite of the good work of the air conditioning system installed in 1999. Part of the humidity did not achieve to condensate and got stuck atop vaults, so a humidity control system was needed.

“This system is integrated by air extractors placed on the domes, accompanied with a detector. A part of the vault was left open, so a natural flue was formed; when wind do not blow with enough strength, the detector is triggered and the humidity control system activated.

“The procedure provokes that saturation caught in the bricks emerges through the dome and not the walls affecting paint”.

The architect remarked that restoration work was conducted by specialists with traditional methods, using quicklime, sand and cactus juice. To paint walls, ceilings and battlement, a mixture of egg whites and quicklime was used; “proofs on exterior have resulted well, it has stayed put for months”.


Museographic Restructuring

Victor Hugo Jasso declared that as part of the constant actualization of the museum’s discourse, and looking forward to the Bicentennial of the Independence commemoration, changes will be done to the hall dedicated to this historical period.

“The new discourse will be more dynamic, addressed mainly to infantile public, by using electronic media; the scientific script, elaborated by INAH National Coordination of Museums and Exhibitions, will strengthen the role of Jose Maria Morelos y Pavon during the taking of San Diego Fort. Collections and illumination system will be modified as well”.

The director of the historical museum remarked that the project presents an advance of 90% and it should be finished in 2010.

He announced that within the context of Independence and Revolution commemorations, temporary exhibitions are being prepared about Jose Maria Morelos, Suriana Insurgency, the Revolution in Acapulco and Insurgents in Latin America, among other themes.
