Arica’s most prominent landmark is this cliff called El Morro. The 427 foot “Nose of Arica” faces the Pacific Ocean. The summit is reached by a pedestrian walkway starting at Colón Street. El Morro was declared a National Monument in 1971. The mount was the last Peruvian stronghold against the Chilean army during the Battle of Morro de Arica in 1880. Learn more about this historic event at the Museo Históricode Armas, a military museum on top of the scarp. You will also see a giant Chilean flag, the Tomb of the Unknown Soldier, the Cristo de la Paz statue, the harbor in the Pacific Ocean and a panoramic view of the city.
