Mercedarian monastery of San Juan de Poio was built in the 17th century and reflects the taste for combining Classicist and Baroque styles. The first document of the monastery on the site is however much older, dating from 942 AD.
Inside, there is a splendid retable from the 18th century, in Churrigueresque style, and the tomb of St. Trahamunda is in the left-hand aisle (much venerated in the district). The procession cloister (16th century) is also noteworthy, with a Baroque fountain and an original stairway. Also worth mentioning are the library, the museum of mosaics, the Escola de Canteiros or the centre for the Summer University courses. The monastery is currently devoted to tourist accommodation, governed by the nuns.
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.
