Schlehdorf Abbey was originally a Benedictine monastery, later an Augustinian monastery, and is today a convent of the Missionary Dominican Sisters of King William's Town.
The abbey, dedicated to Saints Dionysius and Tertullinus, was founded around perhaps 740 from the nearby Benediktbeuern Abbey. In 769 it was resettled by monks from the abandoned Scharnitz Abbey. The first abbot, Atto, brought with him the relics of Saint Tertullinus. It was a Benedictine monastery until the 9th century, after which it is heard of no more; presumably it was destroyed during the Hungarian invasions. From 1140 it was revived as a house of the Augustinian Canons.
In 1803 it was dissolved during the secularisation of Bavaria, and sold off. Since 1904 Schlehdorf has belonged to the Missionary Dominican Sisters of King William's Town. It has been the seat of the German Province of the Order since 1960, and as of 2010 is a community of about 60 Dominican sisters. In the abbey grounds, besides a guesthouse and the abbey shop, is a girls' secondary school of the diocese of Munich and Freising.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.
