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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
