The city of Vyshnivets (in Polish, Wiśniowiec) is a small town about 50 km north of Ternopil. It is mostly known for a large palace that some have called the Versailles of Volyn due to its size and Renaissance style (Volyn –or Volhynia– is an area that contains some of the oldest slavic settlements in Europe.). This complex sits on a steep hill and was developed over the 16th – 17th centuries.
