Tlalpan

Tlalpan is one of the 16 administrative boroughs of Mexico City. It is the largest borough, with over eighty percent under conservation as forest and other ecologically sensitive area. The rest, almost all of it on the northern edge, has been urban since the mid-20th century. When it was created in 1928, it was named after the most important settlement of the area, Tlalpan, which is referred to as “Tlalpan center” to distinguish it from the borough.

This center, despite being in the urbanized zone, still retains much of its provincial atmosphere with colonial era mansions and cobblestone streets. Much of the borough's importance stems from its forested conservation areas, as it functions to provide oxygen to the Valley of Mexico and serves for aquifer recharge. Seventy percent of Mexico City's water comes from wells in this borough.
