You might not have been to the Iris neighborhood unless you live there. North of the river Somes, North even of the train station, you will find the Piața Karl Liebknecht.
There is a mini Christmas market in the Karl Liebknecht square, a trial from 6 December to 11 December.
Here is the important part, the market does not start until 4 pm. A lot of newspapers left that out. If you go around 2pm, only one stall is open.
Many newspapers had photos of the wrong Christmas market, the one in central Cluj, but fortunately, Monitorul had photos of the correct market.
It is a small community market, interesting for locals. From central Cluj however, a few of the roads are currently blocked. If you really want to see it, we suggest going to the train station and taking the tram. If you attempt to walk, bike, or scoot there, you might take an hour longer than your maps app tells you.
