The greystone church of Valö was built in the late 1300s and renovated in the next century. This is a fascinating church to visit, since it has scarcely been altered structurally since the Middle Ages, and contains much interesting inventory from before the Reformation. This includes a processional crucifix from the 15th century and several medieval sculptures. There is also a fine medieval triptych, unusual for a church so small. During a restoration many fine sixteenth century frescoes were uncovered and have since been restored.
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.
