At the southwest corner of the plaza are the Casa de Lavalleja (formerly General Lavalleja's residence), the ruins of the 17th-century Convento de San Francisco and the restored 19th-century faro (lighthouse). At the west end, on de San Francisco, the Museo Municipal has antique homewares, dinosaur remains and huge petrified mushrooms. The Casa del Virrey - which was never home to a viceroy - is just to the north.
