An interesting aspect of the construction of the Palace of the National Library and Museums was the use of iron, a new lightweight and easy-to-assemble material that was ideal for formwork, roofs, reading rooms and library storage vaults. The company Asins, owned by Bernardo Asins, a former royal locksmith, was commissioned to produce the closures and ornamental elements in this new material.
