Church of Santa Maria d'Arenys de Mar Monument · Arenys de Mar, Maresme, Barcelona Baroque parish church of Arenys de Mar, dedicated to Our Lady of the Assumption, whose image presides over the notable altarpiece by Pau Costa on the main altar; it belongs to the diocese of Girona and was consecrated on 28 July 1686. It arose from the separation of the parish of Sant Martí d'Arenys, today Arenys de Munt, of which Arenys de Mar was until then the maritime neighbourhood of La Ribera, because of the difficulty of crossing the stream when it rained and the risk of piracy. On 11 July 1574 the heads of family of La Ribera met at the beach's defence tower, La Fortaleza, and agreed to request permission to build their own church; the bishop of Girona granted it on 18 March 1575, although the rector continued to depend on the mother parish until 1781.
