Akhaltsikhe (Rabati) Castle is a medieval fortress built in the 9th century under the name “Lomsia Castle” in the city of Akhaltsikhe in southern Georgia, recently globally reconstructed. One of the main attractions of the Samtskhe-Javakheti region along with Vardzia.

Akhaltsikhe originally consisted of three parts: the castle, the surrounding citadel and the greater city proper. The castle was surrounded by three ramparts and was connected with adjacent areas by tunnels. Within the citadel, aside from the castle, there was a large courtyard, an arsenal, a mint, a bath and a church. In 1772, Georgian ruler Haji Ahmed-Pasha Jaqeli built a mosque within the castle in the style of the Byzantine Orthodox Church Hagia Sophia of Constantinople using the typical structure of a Georgian Orthodox church, with an added madrasah and a minaret. The mosque functioned for 76 years until 1828. Later, in 1850 by order of the Russian emperor, it was consecrated in the name of the Virgin Mary and functioned as a church for another 92 years until 1920.
