Meteora is a rock formation in central Greece hosting one of the largest and most precipitously built complexes of Eastern Orthodox monasteries, second in importance only to Mount Athos. The six monasteries are built on immense natural pillars and hill-like rounded boulders that dominate the local area. It is located near the town of Kalambaka at the northwestern edge of the Plain of Thessaly near the Pineios river and Pindus Mountains.
Beside the Pindos Mountains, in the western region of Thessaly, these unique and enormous columns of rock rise precipitously from the ground. But their unusual form is not easy to explain geologically. They are not volcanic plugs of hard igneous rock typical elsewhere, but the rocks are composed of a mixture of sandstone and conglomerate.
Caves in the vicinity of Meteora were inhabited continuously between 50,000 and 5,000 years ago. The oldest known example of a man-made structure, a stone wall that blocked two-thirds of the entrance to the Theopetra cave, was constructed 23,000 years ago.
As early as the 11th century, monks occupied the caverns of Meteora. However, monasteries were not built until the 14th century, when the monks sought somewhere to hide in the face of an increasing number of Turkish attacks on Greece. At this time, access to the top was via removable ladders or windlass. Nowadays, getting up is a lot simpler due to steps being carved into the rock during the 1920s. Of the 24 monasteries, only six are still functioning, with each housing less than 10 individuals.
Meteora is included on the UNESCO World Heritage List.References:
Steinvikholm Castle is an island fortress built between 1525 to 1532 by Norway's last Catholic archbishop, Olav Engelbrektsson. Steinvikholm castle became the most powerful fortification by the time it was built, and it is the largest construction raised in the Norwegian Middle Ages.
The castle occupies about half of the land on the rocky island. The absence of a spring meant that fresh water had to be brought from the mainland. A wooden bridge served as the only way to the island other than boat. Although the castle design was common across Europe in 1525, its medieval design was becoming obsolete because of the improved siege firepower offered by gunpowder and cannons.
The castle was constructed after Olav Engelbrektsson returned from a meeting with the Pope in Rome, presumably in anticipation of impending military-religious conflict. As Archbishop Engelbrektsson's resistance to the encroachment of Danish rule escalated, first with Frederick I of Denmark and his successor Christian III of Denmark, Steinvikholm Castle and Nidarholm Abbey became the Catholic Church's military strongholds in Norway. In April 1537, the Danish-Norwegian Reformation succeeded in driving the archbishop from the castle into exile in Lier in the Netherlands (now in Belgium), where he died on 7 February 1538. At the castle the archbishop left behind St. Olav's shrine and other treasures from Nidaros Cathedral (Trondheim). The original coffin containing St. Olav's body remained at Steinvikholm until it was returned to Nidaros Cathedral in 1564. Since 1568 St. Olav's grave in Nidaros has been unknown.
From the 17th to 19th century, the island was used as a quarry and some of its masonry was sold and removed from the site. This activity was condoned by the Danish-Norwegian authorities as a way of eliminating a monument to the opposition of the Danish–Norwegian Union.
Steinvikholm fort is owned and operated today by The society for the Preservation of Norwegian Ancient Monuments. The island has been the site of the midnight opera which details the life and struggles of the archbishop. The opera is held in August annually. The opera is organized by Steinvikholm Musikkteater since the beginning in 1993.
