Alto de la Alianza
Tacna, Peru · built 1982
The Alto de la Alianza Monumental Complex (Complejo Monumental Alto de la Alianza) is a historical monument and landmark complex in the south of Peru, near the city of Tacna. The monument is located at the plateau of the Intiorko (also known as the Alto de la Alianza), a hill that overlooks the city of Tacna. It is specifically located at the site of the Battle of Tacna, which took place on May 26, 1880, between the allied Bolivian and Peruvian forces against the Chilean Army that resulted in the alliance's retreat and the loss of their strongholds in Arica and Tacna, as well as a period known locally as the captivity of Tacna, part of the larger Chilean–Peruvian territorial dispute that lasted about 50 years.
