This square pays tribute to the founding act of San Juan del Río, since, according to the narrative of this fact, it was in this place that the declaration of foundation was made by Juan Mexici, Don Nicolás de San Luis Montañez and Fray Juan Baptist.
For centuries it was the cemetery of the city’s parochial temple, nowadays a kiosk is located at the center of the square and a monument with a cross marks and commemorates the founding of San Juan de Río, an act that is celebrated every year.
