Pielenhofen Abbey for Cistercian nuns, dedicated to the Assumption of the Blessed Virgin Mary, was founded in 1240 by the lords of Hohenfels and Ehrenfels. In 1542, during the Reformation in Pfalz-Neuburg, it was placed under secular administration. In 1655 it was subordinated to Kaisheim Abbey as a sub-priory.
During the secularisation of Bavaria in 1803 the priory was dissolved; the nuns' church became a parish church. In 1806 Carmelite nuns from Munich and Neuburg an der Donau moved into the premises as a joint nunnery. In 1838 the Visitandines, also known as Salesian Sisters, bought it, and established a girls' school here. In 1981 the Pielenhofen Primary School, a boarding school of the Regensburg Cathedral Choir, replaced the earlier school. In 2010 the five remaining nuns moved to the community of the Visitandines at Zangberg.
The Baroque church has two towers of three storeys, two aisles and a transept, under a cupola in the centre. The church contains a late Baroque high altar with eight columns. The ceiling with a depiction of the Holy Trinity is by Jacob Carl Stauder. The pictures of the twelve apostles are by Johann Gebhard of Prüfening Abbey.References:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
