In Voronovytsia we visited the palace of the Grokholsky and Mozhaisky families (XVIII century). There is a park around the palace, but it's in bad condition.
The building hosts a museum of aviation and space exploration history ($1). In 1869-1876 the palace was owned by Alexander Mozhaisky. He developed a model of a kite, which was pulled by three horses and could hold a human in the air. The design was the airframe prototype. This was made 30 years before the Wright brothers' flight. All tests were conducted here, on the banks of the Pivdennyj Bug river.
Getting there: By bus from Vinnytsia towards Uman, Tulchyn, Nemyriv (30 minutes). Stop near the entrance to Voronovytsia, with many cafes and small shops along the road. You will be able to see the palace from a distance; there will also be a pointer to the space museum ("МУЗЕЙ КОСМОНАВТИКИ" in Ukrainian). Then you need to walk about 15 minutes. There is also a direct bus "Vinnytsia - Voronovytsia" that approaches the palace, but it runs rarely. You can ask the locals how to get to the museum ("muzey" in Ukrainian).
