The greystone church in Parainen was built in the 15th century (probably in 1440-1460) and is dedicated to St. Simon. The western part of the Agricola-chapel is the eldest component of the church, today a museum. On the churchyard is located the chapel of bishop Tengström, Finland's first archbishop (erected in 1819). The interior of the church is covered with several coat of arms. The rarest one is dedicated to pope Innocentius III.
National Board of Antiquities has named the church and the surrounding Vanha Malmi old town as national built heritage.
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.
