Abstract: | The former industrial site ‘Parque Fundidora’ in Monterrey, Mexico was turned into a museum site with entertainment facilities. Within these modifications a disused steel mill was converted to a steel museum, showing past and present of the local steelwork industry. The museum opened to the public in the fall of 2007 and was immediately designated a “Monumento Nacional de Mexicox”. One part of the museum complex is the old steel mill that was refurbished and made accessible by open‐air walkways. Another part of the Museo del Acero is a new building that is connected to the existing structure at ground floor level. Due to the site's topography, the new building is partially located underground. Three elements are particularly noteworthy when considering the new building: the facetted roof of the Steel Gallery, a wide‐spanning helical stair, and an extremely transparent glass façade with a lightweight supporting structure made out of steel. These three structures are described in the following article. |
