Ateni Sioni is regarded as the most beautiful church of the "Jvari' type. It is C7th and located in a place of outstanding natural beauty on a rock outcrop above a river in a narrow valley. Its beauty is enhanced by the many reliefs carved into the exterior of the church walls.
Manglisi Sioni church dates back to the C5th and was extended and altered up until the C11th. It was initially centrally planned, but has changed shape significantly over time including the addition of a porch at the west end and another narthex, with a small chapel/shrine open to the elements on one side to the south of the church.
Sioni (Zion) was the most important church in Tbilisi until the new Cathedral of the Trinity was built on the other side of the river. Its foundations date back to late antiquity but it has been continuously altered and been almost completely rebuilt since the end of Communism.
