the early 20th centuries, the monastery was also a place of exile for the opponents of autocracy and official Orthodoxy and a center of Christianization in the north of Russia. The monastery also had a large library of manuscripts and books. The monastery garden also had some exotic flora, such as the Tibetan wild roses presented to the monks by Agvan Dorzhiev, a Lama. After the Bolshevik Revolution and Russian Civil War, the Soviet authorities closed down the monastery and incorporated many of the buildings into Solovki prison camp, one of the earliest forced-labor camps of the gulag during the 1920s and 1930s. "In the earliest years of the Soviet prison system, the Solovetsky Special Prison Camp (SLON) was home to a large group of . . . imprisoned writers." The camp main activity was logging, and when most of the surrounding area had been deforested, the camp was closed. Before the Second World War, a naval cadet school was opened on the island. A small brotherhood of monks has re-established activities in the monastery after the collapse of communism, and it currently houses about ten monks. The monastery has also recently been extensively repaired, but remains under reconstruction. The Solovetsky Monastery is also an historical and architectural museum. It was one of the first Russian sites to have been inscribed in the UNESCO World Heritage List. Layout The Solovetsky Monastery is located on the shores of the Prosperity Bay (бухта Благополучия) on Solovetsky Island. The monastery is surrounded by massive wall 8 to 11 meters high and 4 to 6 meters thick. The wall incorporates 7 gates and 8 towers (built in 1584–1594 by an architect named Trifon), made mainly of huge boulders up to several tonnes of weight. There are also religious buildings on the monastery's grounds with the principal structures interconnected with roofed and arched passages. They are in turn surrounded by multiple household buildings and living quarters, including a refectory (a 500 m² chamber) with the Uspensky Cathedral (built in 1552–1557), Preobrazhensky Cathedral (1556–1564), Church of Annunciation (1596–1601), stone chambers (1615), watermill (early 17th century), bell tower (1777), and Church of Nicholas (1834).
