Cajamarca (kaxaˈmaɾka), also known by the Quechua name, Kashamarka, is the capital and largest city of the Cajamarca Region as well as an important cultural and commercial center in the northern Andes. It is located in the northern highlands of Peru at approximately 2,750 m (8,900 ft) above sea level in the valley of the Mashcon river. Cajamarca had an estimated population of about 226,031 inhabitants in 2015, making it the 13th largest city in Peru. Cajamarca has a mild highland climate, and the area has very fertile soil. The city is well known for its dairy products and mining activity in the surroundings. Among its tourist attractions, Cajamarca has numerous examples of Spanish colonial religious architecture, beautiful landscapes, pre-Hispanic archeological sites and hot springs at the nearby town of Baños del Inca (Baths of the Inca). The history of the city is highlighted by the Battle of Cajamarca, which marked the defeat of the Inca Empire by Spanish invaders as the Incan emperor Atahualpa was captured and executed here. The etymology of the Quechua language name Kasha Marka (Cajamarca dialect), sometimes spelled Cashamarka or Qasamarka is uncertain. It may mean 'town of thorns'. Another theory suggests that it is a hybrid name that combines a Quechua kasha 'cold' and the Quechua marca 'place'. All sources agree that the word has Quechua origin. The city and its surroundings have been occupied by several cultures for more than 2000 years. Traces of pre-Chavín cultures can be seen in nearby archaeological sites, such as Cumbe Mayo and Kuntur Wasi. Huacaloma is an archaeological site located 3.5 km southeast of the historic center of the city of Cajamarca (currently in the middle of the Metropolitan Area of Cajamarca). Its antiquity is calculated between 1500 and 1000 BC, that is to say, it belongs to the Andean Formative Period. It presents enclosures with bonfires, similar to those of La Galgada and Kotosh, but with simpler design. It was a ceremonial center where fire rituals were performed.
