Helenendorf (today Göygöl, Azerbaijan), founded im 1819, was named after the sister of Tsar Alexander I., Helen (in German: Helene). "Dorf" means "village" in German.
"After our stay in Gandschi [editor's note: Gändschä] we visitied Helenendorf, the biggest, most beautiful and richest of the German colonies in the Caucasus.... Our visit turned into a really beautiful, impressive celebration. The village, which was quite big, was decorated by flags and festoons; the church warden greeted us with a speech on the town square where the militia formed a guard of honour; then we were led into the church, where the choir sang and the pastor held a speech. After a genuine Swabian coffee session in the lovely home of the millionaire wine-producing Vohrer family, we went on a tour of the town and visited one of the large winecellars. In the evening there was a celebration in the house of the German society, where both men and women gathered, and there was much talk, music and singing. There was a remarkable amount of pretty girls and women present. For two years the Caucasian wine-growers had not been able to sell their harvests, as there were no opportunities for selling to Russia. A new harvest was approaching, and all barrels were full."
