The Church of Ateni Sioni stands on a shelf, between the villages of Patara Sioni (Little Sioni) and Didi Sioni (Great Sioni). It was built at the beginning of the VIIth century. The main paintings inside were painted in 1080. I will build a page on Church of Ateni Sioni and will put here a link.
The troglodytic city of Uplistikhe stands ten kilometers away from Gori. I will build a page on Uplistikhe and will put here a link.
When we visited, in April, it was windy, raining and the temperature was between 2 and 4°C. Not the best time to visit!
Saint George Gori Jvari is a little church perched on top of a mountain overlooking Gori town, from where you can have great views - so great that Gori would look charming. Getting there is half the fun, as the road is a dirt rack where you can meet all sorts of animals (especially pigs and cows).
The church was closed, unfortunately, so we could only admire it from outside... the belltower is particularly interesting. While you walk up to the church pay attention to the old graves: some are truly finely carved.
Saint George Gori Jvari is about 20-30 minutes drive from Gori. There is no public transportation.
