16th-century chapel built by the Discalced Carmelite Order under the dedication of Saint Sebastian Martyr. The building remained in service until the Laws of Reform were enacted, after which it was abandoned. In 1918, it was whitewashed for its appearance in the film "Santa," based on the novel by Federico Gamboa. In 1939, a neighborhood committee was formed to restore the chapel. The current altarpiece originates from the Church of La Piedad, which was demolished in July 1935.
