Fort Nuestra Senora de la Soledad

Fort Nuestra Senora de la Soledad, near Umatac, Guam, is a fortification built by the Spanish probably in between 1802 and 1819. It was the fourth of four fortifications that protected an anchorage for Spanish galleons transiting between Acapulco, Mexico and the Philippines, a route that fell out of use in 1815 with Mexican independence.
