Hedrum Church was built of stone around 1100 and has 260 seats. The church has a rectangular nave, square choir and apse. Archaeological excavations show that the apse is added later. The structure was extended by four meters in 1666. The west part with the portal and door openings are from after the Reformation. Hedrum Church has a number of tombstones, which cover large parts of the floor of the church. Hedrum Church cemetery is clearly visible from traffic arteries on both sides of Numedalslågen. Some of the graves are believed to pre-date the introduction of Christianity confirming the supposition that ancient pagan cult sites were chosen as the venue for the earlier churches.
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.
