Cerro San Cristóbal, Hill in Rímac district, Peru.

Cerro San Cristóbal is a roughly conical hill between the districts of Rímac and San Juan de Lurigancho in Lima, rising 300 meters above sea level. Its lower and middle slopes are covered with tightly packed rectangular houses in pale colors, while the bare upper slope leads to a summit marked by thin vertical structures, including crosses.

Spanish conquistador Francisco Pizarro named the hill in 1535 and placed a wooden cross at its summit. Inca warriors destroyed this first cross during the siege of Lima, but it was rebuilt afterward.

The hill hosts annual pilgrimages on the first Sunday of May, when thousands of people make their way to the illuminated cross at the summit. This tradition has become an important religious gathering for the local community and draws visitors from across the city.

Small buses called "urbanitos" climb regularly to the summit from Lima's centre, and the hill can also be reached on foot. The slopes were fitted with technified irrigation under Alberto Fujimori, when police recovered the surrounding area. A funicular project was halted after his government fell.

The summit holds a site museum created under Alberto Fujimori's government, when police recovered the surrounding area and the slopes were fitted with technified irrigation. A cable car project linking the Paseo de Aguas to the summit was approved in the early 20th century but was abandoned because few people used it and upkeep cost too much.
