Spa of la Encarnación of Los Alcázares Monument · Los Alcázares, Mar Menor, Murcia Image of Los Alcázares, not of the place itself. Thermal establishment in Los Alcázares dating from 1904 that retains its original structure. The Hotel Balneario de la Encarnación was built in the late 19th century next to the old wooden spa houses raised on the Mar Menor, when the area became a summer destination for the bourgeoisie and farmers from inland, drawn by the therapeutic properties of its waters.
