Baeza is a city and municipality of Spain belonging to the province of Jaén. It is now principally famed for having some of the best-preserved examples of Italian Renaissance architecture in Spain. Along with neighbouring Úbeda, it was added to UNESCO's list of World Heritage Sites in 2003.
Established in the Roman times, the sixteenth century was the golden era of Baeza (and nearby Úbeda). It grew rich from several industries, notably textiles, and the noble families, which were well connected with the Spanish Imperial state. They hired major architects of the era to design the present cathedral, churches, public buildings, and private palaces in the then-fashionable Italian style. The town's university building dates to 1533. The city declined in importance in the seventeenth century, with the only remaining industry consisting of local production of grain and olive oil. As few newer structures were built during this period, this had the effect of preserving the town's Renaissance legacy.
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.
