The first time was in 1767, when expelled the Jesuits from all of Spain and had their property seized, and this building passed to the city. The second came in 1885, when Madrid finally got a diocese of its own and this church served for the time being as its cathedral, a role it would keep for more than a century because the construction of dragged on and on. The third was in , when the interior went up in flames and everything it held in statues and altars was lost.
