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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
