The Coruxo Church is an impeccable example of religious architecture in Vigo with beautiful skylights. Alongside the churches in Bembrive and Castrelos, the Romanesque temple in Coruxo is one of the best preserved in Vigo. The church of San Salvador was built in the 12th century; it belonged to the Benedictines until the 14th century and later became the parish church. Many of its Romanesque art ornaments have been lost: it retains three semicircular apses, but the windows of the central one were walled, thus covering the decorative elements.
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.
