The Iglesia de Nuestra Señora del Buen Suceso, commonly known as Iglesia del Buen Suceso was a church of Madrid that delimited the eastern part of the Puerta del Sol (Madrid). The church comes from a remodeling of the Hospital Real de la Corte (Royal Hospital of the Court) (built in 1483). Was doing functions of church and hospital since 1590. Its lonja was meeting place for several centuries. The church's clock would be important during this period until it was installed one of better performance on the Real Casa de Correos. Its demolition coincided with the Confiscation of Mendizábal that left space for the later expansion that was done for the Puerta del Sol.
