The Metal Building, inaugurated in 1896 and declared Historical and Architectural Heritage, is a unique structure in the heart of San José, built with prefabricated galvanized iron pieces imported from Belgium. Designed by architect Charles Thirion, it stands out for its neoclassical style, ornamental details, and a central courtyard organizing its two levels and symmetrical pavilions. Its 19th-century industrial aesthetic, combined with a bright, functional layout, makes it an ideal location for productions seeking a historical, educational, or period atmosphere with distinctive visual character.
