The Palace of San Telmo is today the seat of the presidency of the Andalusian Autonomous Government. Construction of the building began in 1682 outside the walls of the city, on property belonging to the Tribunal of the Holy Office, the institution responsible for the Spanish Inquisition. It was originally constructed as the seat of the University of Navigators (Universidad de Mareantes), a school to educate orphaned children and train them as sailors.
The palace is one of the emblematic buildings of Sevillian Baroque architecture. It is built on a rectangular plan, with several interior courtyards, including a central courtyard, towers on the four corners, a chapel, and gardens. Presiding over the chapel is an early 17th-century statue of Nuestra Señora del Buen Aire.
The main façade of the palace is distinguished by the magnificent Churrigueresque entrance completed in 1754.
Atop the façade facing Calle Palos de la Frontera, across from the Hotel Alfonso XIII, are sculptures of twelve illustrious Sevillians, sculpted in 1895 by Antonio Susillo.
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.
