The St.Caherine's Church of Muhu is considered one of the most remarkable early-Gothic buildings in Estonia. It was first mentioned in Hermann von Wartberge's Chronicle dated 1276. The exterior architecture of the Muhu Church is a strict monumental style and its originality is prominent. The Muhu Church has preserved its original shape. Around 1663, a little wooden steeple was added to the church, but perished together with the roof in 1941. In 1993, during the restoration period an additional roof was constructed on the facade of the church to protect the church bell.
As for the interior furnishings of the Muhu Church one will find an altar table made of dolomite, which has been preserved from the time of its original construction. Also the stone base of the baptismal basin originates from the Middle Ages.
The pulpit is in Renaissance style and was completed on 1627. It is one of the oldest in Saaremaa and was made by Balthasar Raschky. The Classicist altar was created by Nommen Lorentzen in 1827. The altar painting has survived from the original altar and the painting was finished in 1788.
In the Muhu Church and churchyard there are worth noting the trapezium-shaped tombstones with pagan symbols found only on the islands and Western Estonia. They have been traced to the 12th and 13th centuries. The most intricate tombstone is presently located in the frame of the door leading to the wall staircase. It is one of the two preserved in Estonia from the 12th-13-th centuries depicting human figures. Through discovering tombstones, bones and some other rare archaelogical finds, the church is thought to have been erected on a sacred site of the ancient Muhu inhabitants.
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.
