Panteón de Marinos Ilustres (Pantheon of Distinguished Sailors) began construction in 1786, was inaugurated without a roof in 1870, and covered in 1948. Here rest the mortal remains of many Spanish sailors.
From the exterior of the Pantheon of Illustrious Mariños, the sober and imposing doorway in neoclassical style stands out. Inside, the elliptical-shaped vestibule particularly stands out, as well as the church, with three naves and a dome over the transept. The most important feature inside are the tombs of sailors situated in the sections of the side aisles: Gravina, Álava, Valdés, etc.
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.
