Castle of Dosrius Monument · Dosrius, Maresme, Barcelona Dosrius Castle stands in ruins atop a 246-metre hill, north of the town of Dosrius, in the Barcelona district of the Maresme. It is documented from 1114, contemporary with other fortresses in the area such as Burriac Castle, and until the first half of the 15th century it belonged to the priory of San Pedro de Caserras. Throughout its history it has had three owning lineages: the Dosrius family, between the 12th and 13th centuries; the Castellà family, between the 13th and 15th centuries; and the Sentmenat family, from the 15th century to the present day, the latter being its current owners. Today only its remains survive at the top of the hill, testimony to the strategic importance this Maresme enclave held during the Middle Ages.
