This domed basilica stands in the hills north of Shilda on a track that leads ultimately up into the Caucasus mountains and Dagestan. Although the modern border is now difficult to negotiate, in the past there was a steady traffic of traders and animal herders across the mountains making the now abandoned village of Bartsana, on the open area south of the forest where Sarbela church is located, a prosperous local centre up until the nineteenth century. The church itself has horseshoe arches and the support of the dome is difficult to confirm as the dome has collapsed and within the last 30 years a corrugated metal pyramid has been constructed to protect the building. There are traces of medieval frescoes on the north wall and the north wall of the apse. There is a narthex added to the west side and an additional arcade was appended to the south. The apse is flanked by two pastophoria, the southern of which has ceramics embedded to aid the acoustics. The dome was supported by two piers on the west side and this two-pier disposition was reported by Chubinashvili as being a late development - the same arrangement can be seen at the sixteenth century royal church at Gremi. However this appears to be a late antique foundation, suggesting that the use of piers to support a dome may be earlier in Georgia than previously accepted. Two red crosses were found painted beneath the medieval plaster on the west side of the south pier and in the middle of the north wall. There is an extensive open air marani north of the church.
