The Calahorra Tower is located at Puente Romano, 0. This tower at the end of the Roman Bridge has an interpretation center that explains Moorish culture (Museo Vivo de Al-Andalus). The tower dates from 1369 during the reign of Enrique II. The word Calahorra is Moorish and means "free castle". The building was declared a Monument of Historic and Artistic Interest in 1931. The museum is hosted by the Roger Garaudy Foundation and is devoted to the history of Cordoba from the 9th to the 13th centuries, when Cordoba was at the height of its splendor, when Moors, Jews, and Christians coexisted peacefully. The presentation is audio visual. The top of the tower has a marvelous view of the city and the river.
