"Hermanas Mirabal" ("Mirabal Sisters") were three sisters (Patria, Minerva and María Teresa Mirabal) that lived in Ojo de Agua, a small town in this province, and that were killed on 25 November 1960 by people of the dictator Rafael Trujillo. That day, 25 November, is now known as the "International Day of Non Violence Against Women".
