Saint George's Church was probably founded in 1251. The date was proposed based on an Arabic inscription on a khachkar over the western door of the church yard. According to 13th century chronicler Hovhannes Erznkatsi, the church was built by Prince Umek of Karin.
The church was given to the Persian garrison by Safavid Shah Abbas I of Persia in 1616 and returned to the Armenian community in 1748 by King Heraclius II of Georgia. It was burnt when Persians sacked Tbilisi in 1795. The church was thoroughly restored in the 17th century, and then again in 1832 and 1881.
It became the seat of the Georgian Diocese of the Armenian Apostolic Church after the Vank Cathedral was demolished by Soviet authorities in the 1930s.
The most recent renovation of the church began in 2012 and was completed in 2015.
The church is built on a traditional plan of a partitioned, open cross with a rectangular perimeter. Like most of the churches in Tbilisi, it is built in brick. The outer walls of the church are covered with stucco.
Late 18th-century paintings by Hovnatan Hovnatanian decorate the church's interior. Between 1922 and 1923 Gevorg Bashinjaghian decorated the church's internal walls, the altar, and the walls in front of it, creating four large murals.
The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
