The fountain was originally located in a corner of the garden of the San Antonio convent. The structure supporting the basin was designed by Francisco Eduardo Tresguerras, and the statue of Neptune, the Latin god of the sea, was sculpted by Juan Izguerra. In 1848, a market was built in the convent garden; it was then that the fountain lost two pavilions that flanked the central structure, the back was carved to imitate the front, and the niche became an opening. It is currently located in the Garden of Santa Clara, and the sculpture of Neptune was replaced by a replica made by Abraham González on July 23, 1987. The original has been restored and is kept in a gallery of the Municipal Presidency.
