Viscount of la Armería
Viscount of la Armería () is a hereditary title in the Peerage of Spain, granted in 1694 by Charles II to José de Aldaz y Aguirre, owner of two of the most important armouries in Spain, the "Real Fábrica de Armas de Orbaizeta" and the "Real Fábrica de Municiones de Olaverri", hence the name of the title (armería is Spanish for armoury). It was traditionally held by the heir apparent to the Marquessate of Monte Real, but it was eventually incorporated into the House of Valdueza and is now used by the heir to that title. Viscount
