On the north bank of the Rímac, west of the center of the city of Lima, a large district extends to the north: San Martín de Porres. The district was created by the arrival of immigrants from other parts of Peru, who promised more work and a better life in the capital.
With its university and community facilities, it is above all a residential area of middle class, but it is not a mistake to drag yourself as a visitor outside the central city, it depends on what you are looking for in Lima.
Are you interested in the ancient cultures of Peru? Then you’re right in San Martin de Porres. In the district there are several prehispanic Huacas cultures, including the Huaca El Paraíso and the Huaca Garagay. Both probably originated about 3500 years ago. In Garagay you should admire specially colored reliefs. Of course, the area was much less populated at the time of the creation of the Huacas, today the Huacas are stony places in the midst of urban architecture.
