I’ve found only one hitching ring in Lviv so far. It is attached to the building at 16 Virmenska St. , which was built in 1792 . It looks much older than the ones I found in Lublin , so I think it’s possible that it was installed around the time the building was built, making it approximately 200 years old. For some reason, I can’t find any information about it in any books or on the Internet.
