Bajos de Mena is an urban sector located in the southwest of Puente Alto commune, at the southernmost end of Greater Santiago in Chile. It is a neglected sector of the city of Santiago, with a lot of poverty and overcrowding population. It has about 140 thousand inhabitants, but it lacks various services such as pharmacies, bank branches, among others. It is almost exclusively made up of social housing built under the government of Eduardo Frei Ruiz-Tagle in the 1990s. These characteristics led to the denomination of the "largest ghetto of Chile". In the mid-2010s, this situation gradually began to improve thanks to a comprehensive plan for the sector, which included the creation of the Juan Pablo II Park inaugurated in 2013, the construction of the 66th Carabineros police station inaugurated in 2017, and the demolition and removal of buildings and debris from Villa El Volcán, for the construction of a civic center instead. Due to its large population -similar to cities such as Curicó and Punta Arenas-, its geographic isolation, its lack of services and a considerable distance of 5 km to the civic center of Puente Alto -which is also the most populated commune in Chile-, there are proposals for the sector to achieve communal independence, in conjunction with neighboring parts of La Pintana and San Bernardo.
