The current Bäl church was built during the first half of the 13th century and replaced an earlier stone church on the same site, fragments of which still remain in the wall between the choir and nave. Of the presently visible church, the choir is the oldest part, with the nave and tower being built successively. Paintings were added in the 13th century through 15th centuries. For some reason, the tower was never finished and does not reach its originally intended height.
The church has two portals on the western façade, one leading to the choir and a larger main portal, located on the south side of the nave. The smaller is the older and still Romanesque in style, while the main portal is Gothic, and more profusely decorated. Additionally, there is an entrance on the north façade. The window openings are all original, and have not been enlarged during later centuries.
Inside, the church is decorated by frescos, uncovered in the early 21st century. They depict the Passion of Christ and scenes from the Bible. The church has some medieval items: a triumphal cross (late 13th century), a baptismal font (13th century), and a wooden sculpture depicting Mary. The altarpiece is Baroque, executed in 1664, and the pulpit is from 1744.
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.
