Church of Saint Peter and Saint Paul in Sinichya Gora is one of Russia's oldest churches, dating from 1192. The church is located at the Saint Peter Cemetery, on the left bank of the Volkhov River. It is on the World Heritage list as a part of Historic Monuments of Novgorod and Surroundings. The small stone church is built as a cube and has one dome. The type of a small church was developed in Novgorod in the end of the 12th century, and there are several churches of this type, in Novgorod and in Staraya Ladoga.
The church was built collectively by the inhabitants of the former Lukina Street, and was a part of the female Saints Peter and Paul Monastery. The monastery was plundered in 1611 by Sweden during the Time of Troubles and never recovered, finally being abolished in 1764. After the monastery was abolished, the church was converted into a cemetery church. It is the only surviving monastery building. It was closed for service in 1925 and fell into increasing dilapidation, though currently it is undergoing a restoration.
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.
