First mentioned in historical records in 1327. 

Olesky Castle is now a big museum that you can walk around and enjoy. They even have a functioning draw bridge at the entrance! After it lost its importance as a defense castle it came to be a privately-owned castle and was sold to a few different people. It was treated badly though until 1682 when it was given a proper renovation. It was the birth place of the polish kind Jan III Sobieski and it is said the Boghdan Khmelnitsky spent much of his childhood here. It was considered a Polish National Monument and was restored again in 1882. The two World Wars took their toll on the building and it had to be restored again in 1952. Now it houses a museum with art from the 16th and 17th centuries.
