Current Primary School No. 16 «Vicente López y Planes», former place of the Monte chapel built in 1831 by the Governor Juan Manuel de Rosas.

The school N ° 16 of San Miguel del Monte, has under its structure the foundations of the church that Rosas had built in 1831, in front of the main square, and that was demolished after its defeat in the Battle of Caseros; The schoolyard had already sunk three times, and before remodeling it, the mayor of San Miguel del Monte, Laura Giagnacovo de Gallardo, decided to call the cultural institute of the province of Buenos Aires. A group of archaeologists began the excavations and discovered that the Monteses were not wrong. Brick walls and semicircular arches appeared. The excavations reached a depth of 2.60 M and could not determine the reason for the arches «It is possible that they were a reservoir for water and food or a series of passageways, tunnels built to escape or to contact another place,» said archaeologist María Inés Casada. It is possible that they could have designed it to protect themselves from the malones.

Among the more than 10,000 objects that they found there are other weapons of wars “We found a huge amount of things: slab and ceramic utensils, inkwells, beer bottles, a jaw of a ruminant mammal, a Roskoff watch, cups, plates, cutlery, coins, remains of wooden and leather footwear, Irish bottles from the 1800s, ”said María Eugenia Peltzer, other archaeologists in charge of the project.
