It has this name because this was the Plaza Mayor of the City Hall of San Luis Potosi during the Viceroyalty, where the Royal Houses were located and where the Coat of Arms of the City was located.
The Jardín Hidalgo did not exist as such until the end of the 19th century when the obelisk of Tres Guerras was changed into a monument to the priest Miguel Hidalgo. This Square and Garden was later a meeting place for Potosinos from the 17th century to the present day, where battles for freedom, power and democracy took place.
