Metekhi was one of the earliest inhabited areas on the Tbilisi's territory. According to traditional accounts, King Vakhtang I Gorgasali erected here a church and a fort which served also as a king’s residence; hence comes the name Metekhi which dates back to the 12th century and literally means “the area around the palace”. Tradition holds that it was also a site where the 5th-century martyr lady Saint Shushanik was buried. However, none of these structures have survived the Mongol invasion of 1235.
The extant Metekhi Church of Assumption, resting upon the top of the hill, was built by the Georgian king St Demetrius II circa 1278–1284 and is somewhat an unusual example of domed Georgian Orthodox church. It was later damaged and restored several times. King Rostom (r. 1633-1658) fortified the area around the church with a strong citadel garrisoned by some 3,000 soldiers. Under the Russian rule (established in 1801), the church lost its religious purpose and was used as a barracks (R. G. Suny, p. 93). The citadel was demolished in 1819 and replaced by a new building which functioned as the infamous jail down to the Soviet era, and was closed only in 1938.
The Metekhi church is a cross-cupola church. While this style was the most common throughout the Middle Ages, the Metekhi church is somewhat anachronistic with its three projecting apses in the east facade and the four freestanding pillars supporting the cupola within. The church is made of brick and dressed stone. The restoration of the 17th, 18th, and 19th centuries mostly employed brick. The facade is for the most part smooth, with decorative elements concentrated around the windows of the eastern apses. Horizontal bands below the gables run around all four sides and serve as a unifying element. The north portico of the main entrance is not a later addition but was built at the same time as the rest of the church.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.
