Rímac River in the context of Ricardo Palma District

Lima is the capital and largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín Rivers, in the desert zone of the central coastal part of the country, overlooking the Pacific Ocean. The city is considered the political, cultural, financial and commercial center of Peru. Due to its geostrategic importance, the Globalization and World Cities Research Network has categorized it as a "beta" tier city. Jurisdictionally, the metropolis extends mainly within the province of Lima and in a smaller portion, to the west, within the Constitutional Province of Callao, where the seaport and the Jorge Chávez Airport are located. Both provinces have had regional autonomy since 2002.

The 2023 census projection indicates that the city of Lima has an estimated population of 10,092,000 inhabitants, making it the second-most populous city in South America and the largest Spanish-speaking city in the world in terms of city proper population. The Lima Metropolitan Area, which forms a contiguous urban area with the seaside city of Callao, has a population of 10,151,200 inhabitants. When considering the additional 6 districts contained in the Constitutional Province of Callao, the total agglomeration reaches a population of 11,342,100 inhabitants, one of the most populated urban agglomerations in the world. The city is marked by severe urban segregation between the poor pueblos jóvenes, populated in large part by immigrants from the Andean highlands, and wealthy neighborhoods.

The Chancay were a pre-Hispanic archeological civilization that developed between the valleys of Fortaleza, Pativilca, Supe, Huaura, Chancay, Chillón, Rimac and Lurín, on the central coast of Peru, from about 1000 to 1470 CE.

Lurigancho is a district of Lima, Peru. It is located in the valley of the Rímac River, which it shares with neighboring Chaclacayo and Ate districts. Its capital is the town of Chosica, located 861 m (2,825 ft) above sea level.

The Walls of Lima were a fortification consisting mainly of walls and bastions whose purpose was to defend the city of Lima from exterior attacks. It was built between 1684 and 1687, during the Viceroy Melchor de Navarra y Rocafull (Duke of Palata)'s government.

The wall was located on the present streets of Alfonso Ugarte, Paseo Colón and Grau and the left bank of Rímac River. Under Luis Castaneda Lossio's management, he recovered a section of the remains of the left bank of the Rímac River, which are now visible as a part of the group known as "Parque de la Muralla," although these are probably from a previous construction known as "Tajamar de San Francisco." The Santa Lucía bastion is a sector of the wall located on the edge of Barrios Altos and El Agustino that still stands .

Carabayllo (Spanish pronunciation: [kaɾaβaˈiʝo]) is one of the 43 districts of the province Lima in Peru. It is located in the Cono Norte area of the province and was created district by General José de San Martín in August 4, 1821 at which time it was the only district to occupy the area north of the Rímac River up to the province Canta.
