Rokantiškės Castle was located east of Vilnius on a high hill near the Vilnia River. First castle was built in 12th century. In 16th century, it was rebuilt in the Renaissance style and has been the seat of the Olshanski family. Alexander Olshanski, Yuri Olshanski and the last family member Pawel Olshanski have lived there. After his death the castle was inherited by Bona Sforza and later passed to the Pac family. The Deputy Chancellor of Lithuania Stefan Pac was visited here by the King of Poland and Grand duke of Lithuania Władysław IV Vasa on July 15, 1636.
The castle was burnt down by Cossacks on August 7, 1655 during the Russo-Polish War and fell in ruins. Today there are the only visible medieval castle ruins in Vilnius.
