The city of San Lorenzo preserves the site of the battle and a dedicated historic complex. The San Carlos Convent is still a working convent, but has turned part of its buildings into a museum. It has retained San Martín's cell, the room used for medical treatment of the injured soldiers, urns of the dead soldiers and other related items to the "March of San Lorenzo" as well as the history of the convent. The mayor of San Lorenzo, made an agreement with the Argentine Armed Forces in 2008 that the Regiment of Mounted Grenadiers would have a permanent presence at the site.
