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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
