La Magdalena is a Gothic-style, Roman Catholic church located in the city of Jaén. The church was built atop the foundations of a mosque that had been erected in 825 by Abd ar-Rahman II. The present bell-tower was the former minaret, putatively redesigned by Andrés de Vandelvira. The pool in the cloister was used by Muslim worshipers prior to entering the building. Outside in the plaza is a pool with the statue of the Lizard of Jaén (Lagarto de Jaén), depicting a legendary monster of the area.
The church a main nave and three aisles, separated by arches that are spanned by ribbed vaults. The portal has Isabelline Gothic decoration. The church includes a polychrome sculptural group depicting the Calvary attributed to Jacobo Florentino or Jerónimo Quijano; a Christ of the Mercy (1593) by Salvador de Cuéllar; and a Kneeling Magdalen (1572) by Mateo Medina. The church has a number of 17th and 18th-century canvases. The main portal doors were carved in 1555.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
