According to experts, Tsromi Temple represented a new stage in Georgian church architecture after the cross-type churches. Its artistic value is seen as equivalent to that of Mtskheta’s Jvari Church.
Over the centuries, the temple has been damaged many times, but the restoration work done in 1949, 1959, and the mid-70s have restored it to its original state.
The altar of the temple used to be decorated with a mosaic of leaf ornamentation, along with a representation of Christ holding an unfurled scroll with a seven-line inscription in ancient Georgian Asomtavruli script in his left hand, and issuing a blessing with his right, while angels stand to the side.
The remaining walls and dome of the church are unpainted, although there were once frescoes depicting the Ascension of Christ. These were taken down in 1932 to be preserved, and can now be found in an Shalva Amiranashvili Museum of Arts.
