The St. Mary’s Church in Rõuge was originally built in 1550, but it was damaged badly in the Great Northern War. The present church was reconstructed in 1730’s. In 1854 the church obtained its organ and the altar picture of 'Christ on the cross' by R. von Mühlen.
In 1860 the building was completely renovated, with the walls being made higher and a mirrored arch installed. The Kriisa brothers donated a 31-register organ they had built to the church in 1930. The first Estonian pastor in Rõuge was Rudolf Gottfried Kallas.
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.
