Praza da Ferrería has the best selection of cafes (as opposed to bars) in town. It's overlooked by the 14th-century Igrexa de San Francisco , said to have been founded by St Francis of Assisi when on pilgrimage to Santiago. Just off the plaza, you can't miss the distinctive curved facade of the Santuario da Virxe Peregrina , an almost circular 18th-century caprice with a distinctly Portuguese flavour.
