The imposing red brick church in Keldby is one of the three Møn island churches decorated with frescos by the Elmelunde Master, probably towards the end of the 15th century. In the so-called Biblia pauperum style, they present many of the most popular stories from the Old and New Testaments. There are also a number of earlier frescoes in the church dating back to about 1275.
The original nave and choir were constructed in the first half of the 13th century. Around 1480, the nave was expanded with cross vaults and the choir was heightened with limestone. The tower was added in the 16th century and a small sacristy was built about 1700. The richly carved altar triptych and the pulpit are from 1586.
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.
