Bälinge Church is a medieval church in Bälinge, Uppsala Municipality. The church was built at the end of the 13th century and has been substantially altered on several occasions. It derives much of its present appearance from changes made during the 18th century and during a large reconstruction carried out in 1874-88.
The church interior contains two sets of murals, one dating from the early 15th century and another made later in the same century by the workshop of Albertus Pictor or an artist influenced by him. The church also contains two notable medieval altarpieces, one of which may originally have been placed in Uppsala Cathedral as a side altar.
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.
