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.
Czocha Castle is located on the Lake Leśnia, what is now the Polish part of Upper Lusatia. Czocha castle was built on gneiss rock, and its oldest part is the keep, to which housing structures were later added.
Czocha Castle began as a stronghold, on the Czech-Lusatian border. Its construction was ordered by Wenceslaus I of Bohemia, in the middle of the 13th century (1241–1247). In 1253 castle was handed over to Konrad von Wallhausen, Bishop of Meissen. In 1319 the complex became part of the dukedom of Henry I of Jawor, and after his death, it was taken over by another Silesian prince, Bolko II the Small, and his wife Agnieszka. Origin of the stone castle dates back to 1329.
In the mid-14th century, Czocha Castle was annexed by Charles IV, Holy Roman Emperor and King of Bohemia. Then, between 1389 and 1453, it belonged to the noble families of von Dohn and von Kluks. Reinforced, the complex was besieged by the Hussites in the early 15th century, who captured it in 1427, and remained in the castle for unknown time (see Hussite Wars). In 1453, the castle was purchased by the family of von Nostitz, who owned it for 250 years, making several changes through remodelling projects in 1525 and 1611. Czocha's walls were strengthened and reinforced, which thwarted a Swedish siege of the complex during the Thirty Years War. In 1703, the castle was purchased by Jan Hartwig von Uechtritz, influential courtier of Augustus II the Strong. On August 17, 1793, the whole complex burned in a fire.
In 1909, Czocha was bought by a cigar manufacturer from Dresden, Ernst Gutschow, who ordered major remodelling, carried out by Berlin architect Bodo Ebhardt, based on a 1703 painting of the castle. Gutschow, who was close to the Russian Imperial Court and hosted several White emigres in Czocha, lived in the castle until March 1945. Upon leaving, he packed up the most valuable possessions and moved them out.
After World War II, the castle was ransacked several times, both by soldiers of the Red Army, and Polish thieves, who came to the so-called Recovered Territories from central and eastern part of the country. Pieces of furniture and other goods were stolen, and in the late 1940s and early 1950s, the castle was home to refugees from Greece. In 1952, Czocha was taken over by the Polish Army. Used as a military vacation resort, it was erased from official maps. The castle has been open to the public since September 1996 as a hotel and conference centre. The complex was featured in several movies and television series. Recently, the castle has been used as the setting of the College of Wizardry, a live action role-playing game (LARP) that takes place in their own universe and can be compared to Harry Potter.
