Because of its location, the collegiate church of Santa Cruz de Castañeda came to be part of the Pilgrim's Road to Santiago de Compostela. The existing building is from the 12th century, although the church, in Romanesque style, and a monastery, previously stood on the site.
Initially its plan had one nave and three apses, but it was later altered, adding 2 naves to the structure. One of them is in the Gothic style and the other later (17th century). They transformed the southern apse into a private chapel and sacristy in the Baroque style. On the capitals of the columns, which are preserved in perfect condition, the animal and vegetable iconography is outstanding. The Gothic Way of the Cross (there are no others like it in all Cantabria) the Baroque reredoses and 2 carvings of the Virgin with Child must not be missed.
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.
