Úbeda is a municipality of Spain located in the province of Jaén. Both this town and the neighbouring Baeza benefited from extensive patronage in the early 16th century resulting in the construction of a series of Renaissance style palaces and churches, which have been preserved ever since. In 2003, UNESCO declared the historic centres and landmarks of these two towns a World Heritage Site.
The most outstanding feature of the city is the monumental Vázquez de Molina Square, surrounded with imposing Renaissance buildings such as the Palacio de las Cadenas (so named for the decorative chains which once hung from the façade) and the Basílica de Santa María de los Reales Alcázares. The Chapel of the Savior or Capilla del Salvador was constructed to house the tombs of local nobility. Both the interior and exterior are decorated; for example, the interior has elaborate metalwork screen by the ironworker Bartolomé de Jaen. The Hospital de Santiago, designed by Vandelvira in the late 16th century, with its square bell towers and graceful Renaissance courtyard, is now the home of the town's Conference Hall. Úbeda has a Parador hotel, housed in a 16th-century palace which was the residence of a high-ranking churchman of that period.
The city possesses 48 monuments, and more of another hundred of buildings of interest, almost all of them of Renaissance style.
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.
