Sanok is a Polish city located in the Carpathian Mountains. Historically, the region was inhabited by Lemkos and Boykos. In the interwar period, the city was known as a center of the Ukrainian movement in Galicia, and of the cultural heritage of Lemkos and other Rusyns.
I didn’t spend much time in Sanok and didn’t come across any remnants of the Ukrainian or Lemko heritage. However, right outside the city is a beautiful skansen, an outdoor museum of folk culture of the Lemko people.
As for other traces of the past, I found a few ghost signs there, but I think some could be from after WWII.
