La Concha Acústica is an open-air auditorium oftentimes used as a music venue, including presentations by the Ponce Municipal Band.

During the 18th century, as gold mining ceased to be one of the major industries in Puerto Rico, slaves worked mostly in coffee plantations and sugar cane fields.

In 1874, a year after the abolition of slavery in Puerto Rico, a group of citizens built a small park in memory of the historic event.

In 1880 Olimpio Otero, Juan Mayoral Barnés, and Román Baldorioty de Castro were instrumental in creating the concept for a park dedicated to commemorating the abolition of slavery, the only such memorial in the Caribbean.

The renovation included the building of Concha Acustica de Ponce and the addition of the statue to stand at the base of the obelisk, in front of it.
