This 14C monastery, closely linked to the history of the discovery of America, is the largest Mudéjar-Gothic building in Huelva province. The church is the epitome of sobriety, despite the juxtaposition of different styles, from Mudéjar through to Renaissance. In front of the main altar and in the side niches, the tombs of Beatriz Henríquez and the Portocarrero family, the lords of Moguer, are the most interesting sights of interest.
