modified by 1860 due to the Reform Laws, in part to allow for the construction of the Cristóbal Colon Primary School and the Andrés Quintana Roo Library. In the second half of the 19th century, the first project to drain Lake Chalco was undertaken. However, the endeavor would not be finished until the era of Porfirio Diaz in the late 19th century and early 20th. The village of Mixquic became integrated with the Mexico City area in 1898, which would have long-term implications, as city authorities would have control over the community's resources, in particular, its water. In 1916, during the Mexican Revolution, the monastery was occupied by forces loyal to Venustiano Carranza. In the first half of the 20th century, the community managed to preserve many of its chinampas using well water but by the 1960s, this was no longer feasible, ending the community's lake culture. However, farming is still a major economic activity here and is the main producer of vegetables in the Federal District. The community is about three km2 with most of it used for agricultural purposes. Over half of this land is ejido. Most of the produce is sold at the giant Centro de Abastos food market in the city. Life is changing for the community as it becomes more integrated with Mexico City proper. More private vehicles and more public transportation is available, leading more of the community's younger generation to seek employment in the city and/or further their education at university.

The first church was demolished with only the original bell tower remaining. The current church dates from 1600, built with three naves and a cupola, but it is separate from the bell tower of the original church.

In the courtyard of the old monastery, there are a number of pre-Hispanic archeological finds on display. The first is a sculpture of Miquiztli or Mixquixtli, the goddess of life and death. Another significant find is a Chac Mool which is
