Kizhi Pogost is a historical site dating from the 17th century on Kizhi island. The pogost is the area inside a fence which includes two large wooden churches (the 22-dome Transfiguration Church and the 9-dome Intercession Church) and a bell-tower. The pogost is famous for its beauty and longevity, despite that it is built exclusively of wood. In 1990, it was included in the UNESCO list of World Heritage sites and in 1993 listed as a Russian Cultural Heritage site.
The Church of the Transfiguration is the most remarkable part of the pogost. It is not heated and is therefore called a summer church and does not hold winter services. Its altar was laid June 6, 1714, as inscribed on the cross located inside the church. This church was built on the site of the old one which was burnt by lightning.
The church has 22 domes and with a height of 37 meters is one of the tallest wooden buildings of the Russian North. According to the Russian carpentry traditions of that time, the Transfiguration Church was built of wood only with no nails. All structures were made of scribe-fitted horizontal logs, with interlocking corner joinery — either round notch or dovetail — cut by axes. The basis of the structure is the octahedral frame with four two-stage side attachments. The eastern prirub has a pentagonal shape and contains the altar. Two smaller octagons of similar shape are mounted on top of the main octagon. The structure is covered in 22 domes of different size and shape, which run from the top to the sides. The refectory is covered with a three-slope roof. In the 19th century, the church was decorated with batten and some parts were covered with steel. It was restored to its original design in the 1950s.
The iconostasis has four levels and contains 102 icons. It is dated to the second half of the 18th – early 19th century. The icons are from three periods: the two oldest icons, 'The Transfiguration' and 'Pokrov' are from the late 17th century and are typical of the northern style. The central icons are from the second half of the 18th century and are also of the local style. Most icons of the three upper tiers are of the late 18th century, brought from various parts of Russia.
The Church of the Intercession is a heated winter church. The church was the first on the island after a fire in the late 17th century destroyed all previous churches. It was first built in 1694 as a single-dome structure, then reconstructed in 1720–1749 and in 1764 rebuilt into its present 9-dome design as an architectural echo of the main Transfiguration Church. There are nine domes, one larger in the center, surrounded by eight smaller ones. Decoration is scant. A high single-part porch leads into the four interior parts of the church. As in the Transfiguration Church, the altar is placed in the eastern part shaped as a pentagon. The original iconostasis was replaced at the end of the 19th century and is lost; it was rebuilt in the 1950s to the original style.
The original bell-tower rapidly deteriorated and was rebuilt in 1862 and further reconstructed in 1874 and 1900. The fence was built in the 17th century as a protective measure against Swedish and Polish incursions. It was reconstructed in the 1950s as a 300-meter-long log structure surrounding the two churches and the belfry. The structure rests on a tall boulder basement. The main entrance is 14.4 meters wide and 2.25 meters tall, and faces east near the Church of the Intercession. There are wicket gates at the eastern and northern sides and a small wooden tower in the north-western corner. The tower has a square base and a four-slope batten roof with a spire. The walls, gates and wickets are also roofed.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
