Savigny Abbey (Abbaye de Savigny) was founded by Vital de Mortain, who set up a hermitage in the forest of Savigny (1105). Rudolph, lord of Fougeres, confirmed to the monastery (1112) the grants he had formerly made to Vital, and from then dates the foundation of the monastery. Its growth was rapid, and Vital and Saint Aymon were canonized.
In 1119 Pope Celestine II, then in Angers, took it under his immediate protection, and strongly commended it to the neighbouring nobles. Under Geoffroy, successor to Vital, Henry I of England established and generously endowed 29 monasteries of this Congregation in his dominions. Bernard of Clairvaux also held them in high esteem, and it was at his request that their monks, in the times of the antipope Anacletus, declared in favour of Pope Innocent II.Serlon, third successor of the Founder, found it difficult to retain his jurisdiction over the English monasteries, who wished to make themselves independent, and so determined to affiliate the entire Congregation to Citeaux, which was effected at the General Chapter of 1147. Several English monasteries objecting to this, were finally obliged to submit by Pope Eugene III (1148).
In later centuries discipline became relaxed. In the mid-16th century the Abbey was pillaged and partly burned by Calvinists, and records of the following year mention but twenty-four monks remaining.It continued to exist until the Revolution reduced it to a heap of ruins, and scattered its then existing members. The church was restored in 1869. It has been listed as a Monument historique by the French Ministry of Culture in 1924.

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.
