Sommeregg is a medieval castle near Seeboden situated in the foothills of the Nock Mountains. The castle was probably erected in the 12th century. The Lords of Sommeregg then served as ministeriales of Count Otto II of Ortenburg, who ruled over extended estates in Upper Carinthia, rivalling with the House of Gorizia and the Salzburg archbishops.
In the 14th century, the Lords of Sommeregg achieved the knightly status of Ortenburg burgraves and castellans with comprehensive administrative and military responsibilities in the lordship of the manor. When the Counts of Ortenburg became extinct in 1418, their possessions passed to the Counts of Celje in Carniola, who left the administration of the remote Upper Carinthian estates to local stadtholders. In 1442 the Styrian noble Andreas von Graben by marriage inherited the Sommeregg burgraviate. His rights were acknowledged by Count Frederick II of Celje and the castle became a residence of the House of Graben.
The dynasty maintained the title of Sommeregg burgraves, even when the last Celje count Ulrich II was murdered in 1456. After a long dispute with Count John II of Gorizia, the former Ortenburg possessions fell to the Habsburg emperor Frederick III, who confirmed the feudal rights of the Graben family. Andreas von Graben was succeeded by his son Virgil in 1463, however, in 1487 the castle was occupied and devastated by Hungarian forces under King Matthias Corvinus on his campaign against the Austrian Habsburgs. Afterwards Virgil von Graben had the fortress rebuilt in its current appearance.
Through Virgil's niece and heiress Rosina (d. 1534), Sommeregg passed to the Bavarian Lords of Rain. In 1550 it was purchased by the Carinthian noble Christoph Khevenhüller, whose descendants held the castle until 1628. The Sommeregg manor was dissolved upon the Revolution of 1848.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
