This chapel was called the Hospital of the Holy Trinity when it was built in 1685. Ten years later, Clemente de Cáceres founded Our Lady of Mercy and Holy Rosary. This evolved into the Brotherhood of Our Lady of Socorro. It is based on a Marian appearance when a sinner was running from a lynch mob, cried out for help on the chapel steps and was miraculous hidden. A centuries-old carving of La Virgen del Socorro (Virgin of Help) is displayed on the altar of Hermandad del Socrro. Each year, the religious icon is marched through the streets of Córdoba in a festive procession.
