Tacna is a city in southern Peru. Inland from the Pacific Ocean and in the valley of the Caplina River. Tacna is a very commercially active city, located only 35 km (21 miles) north of the border with Chile. Tacna is served by the Carlos Ciriani Santa Rosa International Airport

Officially called San Pedro de Tacna, it has gained a reputation for patriotism, with many monuments and streets named after heroes of Peru's struggle for independence (1821-1824) and the War of the Pacific (1879-1883). Residents of Tacna are known in Spanish as tacneños. Many monuments are located in this city, including the arch of the Alto de la Alianza, which shows the significance of this town. Other monuments include a neo-Renaissance Cathedral, the Alameda Bolognesi Walkway and the caves of Toquepala, where archaeologists have found some of the oldest human remains in Peru.

The most important festivity in the city is the Semana de Tacna ("Tacna Week"), which runs from August 25-30. On August 28, a large Peruvian flag is shown throughout the city during the Paseo de la Bandera, which celebrates the anniversary of the reincorporation of Tacna into Peruvian sovereignty. This tradition started in 1901 by a group of tacneños who defied the prohibition and the Chilean occupation. In September, the festival of the Señor de Locumba is celebrated, which draws thousands of faithful people from all over the world
