The name of the city came from an old 18th century legend. At that time, there was a brave horse, incredibly beautiful and defiant, who went to the lagoon to drink water.
The natives and the soldiers of the Argentine Army (who were exploiting and trying to take control of the lands from the native people), wanted to tame the horse. There were many attempts to catch it, but the horse was brave and it was always fighting, defending its freedom. One day, a group of soldiers corner it against the lagoon, in a ravine, and when they were sure that it had no escape, the horse jumped to the water, killing itself. It preferred death to captivity.
The libertarian spirit of the horse was so amazing that the legend of the Bragado horse spread around the place and gave name to the city.
