Pechersky Voznesensky Monastery is usually said to have been founded ca. 1328-1330 by St. Dionysius, who came to Nizhny Novgorod from Kiev Pechersk Lavra (i.e., Kiev Monastery of the Caves, pechery meaning 'caves') with several other monks, and dug for himself a cave on the step Volga shore some 3 km southeast of the city. Later on, he founded at that site a monastery with a church of Resurrection of the Lord.
The monastery soon became an important spiritual and religious center of the Principality of Suzdal and Nizhny Novgorod. The monastery was destroyed by a landslide on June 18, 1597; surprisingly, no one died. The same year the monastery was rebuilt about 1 km upstream (north) of the old site.
Although there are no caves in the modern monastery, the appellation Pechersky, linking it to the old Kiev cloyster, has been preserved. Moreover, the entire section of Nizhny Novgorod surrounding the monastery, occupying uplands above the Volga south of the city center, is known as Pechery.
The monastery was closed by NKVD in 1924, and reopened in 1994.
The current Ascension Cathedral is constructed in 1630—1632.The Church of Dormition of Our Lady dates from 1648 and the church of Saint Venerable Euthimios of Suzdal from 1645.The other buildings date from the 17th and 18th centuries. The belfry of the Ascension Cathedral (which also serves as a clock tower) is noticeably out of plumb. It has been leaning almost since the time it was originally constructed. The monastery is surrounded by a red brick wall with small towers, making it look like a small kremlin. The diocesal archeological museum and a book and icon shop operate in the monastery.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.
