The monastery of San Salvador de Celanova was founded by St. Rudesind (San Rosendo) in 936. The jewel of the complex is the small mozarabic chapel of San Miguel, dating from 942. In the garden is one of the oldest chapels in Spain, built before 973.
In the abbey church are the ancient sepulchres of Ilduara and Adosinda, the mother and sister of the founder, who was buried in a sepulchre supported on four pillars, and constructed after the fashion of that of San Torcuato, one of the companions of Santiago. His body was deposited by the Christians, at the Moorish invasion, at Santa Coinba, 16 km away. Being near the frontier, some Portuguese carried it off and brought it to Celanova, whose bells began to ring of their own accord.
There are two cloisters. El Processional has columns, a fountain and railing, while El Puleiro includes a sala capitular and brick mosaic pavement. The Doric church has two separate choirs, featuring a carved door and walnut silleria. There are many memorials.
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.
