House of Simancas
“Archivum Regni”
Origin: Lords of Simancas, keepers of Spain's royal archive
The lords of Simancas administered the fortress that Philip II chose to house the General Archive of the Realm—the most important documentary collection in Spanish history.\n\nThe archive contains millions of documents spanning the Spanish Empire, from Columbus's letters to Inquisition records. The family's castle became the memory of an empire.\n\nBefore the archive, the castle served as a prison and military stronghold controlling the approaches to Valladolid.
