The Church of the Trinity and San Giovanni is a Romanesque and Pisan-style building from the 11th century. In the church's chapel, two murals depicting Doctors of the Church and Saint George slaying the dragon date from 1449 and 1458 respectively. In 2011, an archaeological evaluation was carried out on the church's nave in favor of a restoration campaign.
Like the chapels at Montegrosso and Lumio, the chapel is located in the center of the cemetery and is decorated with human and animal figures (including bears, oxen and snakes). One example is in the pinion in the vertical alignment of the door: it depicts a man removing a thorn from his foot; this is an allegory of knowledge and is fairly widespread in Romanesque buildings.
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.
