Hangvar church dates from the 13th century. The oldest parts are the choir and nave; the tower was built slightly later. The church has a decorated entrance portal, with sculpted capitals and a sculpture of a man's head above the portal. Internally, the church ceiling is supported by four vaults which rest on a central column. The base of the column is decorated with carved figures. Among the furnishings, the baptismal font is medieval, dating from circa 1250. The church has originally been decorated with six wooden sculptures dating from the Middle Ages but these are now displayed in the Gotland Museum in Visby. The altarpiece, made of wood, dates from 1684, while the pulpit is from 1633.
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.
