The Plaza Madero was originally the main square of the congregation of Irapuato. The important religious and commercial buildings were located around this square, for example: the parish (now the cathedral) and the arcades. It was not until the 20th century that it was named Plaza Madero, in honor of Francisco I. Madero, the initiator of the Mexican Revolution.

In this place you can see the Fountain of the Dolphins or Florentine Fountain. According to the chronicler Genaro Acosta, the fountain was brought from Guanajuato in the mid-19th century (c. 1857) at the request of the political chief of Irapuato, Colonel Francisco Rocha (father of the celebrated General Sóstenes Rocha).

The fountain was initially placed in the Plaza de la Tanda (today Plaza Hidalgo) until it was placed here in the mid-forties. There is a similar fountain in the Plaza del Baratillo in the city of Guanajuato.
