The palace of Polish magnates Grokholskiy has been preserved in Voronovitsya, in the middle of an ancient park. It was constructed in the 1770s in the style of early Classicism by the project of the German architect L. Gedon. The customer was Count Francisc Grokholskiy, a senior official at the court of the Polish king Stanislaw August.

The palace consists of a three-storied central building with symmetrically attached two-storied arched wings. These curved structures indicate that the architect borrowed certain motives from Italian architecture of the times of Andrea Palladio (16th century).

The main facade is accented by a portico with eight Corinthian columns. The stucco with flowers and fruits that decorates the facade has been preserved.

The estate belonged to the Grokholskiy family for about 100 years since the middle of the 18th century. The palace was luxuriously furnished and had a rich collection of paintings by European artists. A park in the regular French style was arranged around the buildings.

In 1869, the last owner of the estate, Lyudhard Grokholskiy, was forced to sell his property under the pressure from the Russian government. The buyer was captain II rank Mykola Fedorovych Mozhaiskiy. Soon he died tragically and his brother Oleksandr arrived to Voronovitsya. Now he is known as a pioneer of the aviation, and the inventor of the first Russian aircraft. Mozhaiskiy lived in Voronovitsya for seven years. Here, he constructed models of aircraft and tested them.

Today the palace houses the Voronovitsya Museum of Aviation and Astronautics. Its expositions tell us about the development of domestic aviation from the most primitive models of gliders and airplanes to spaceships. They also give detailed coverage of Mozhayskiy’s activities in this field, and tell the story of military aviation. The halls of the museum devoted to modern times describe the current situation in Ukrainian aviation and the country’s contribution to development of global space exploration programs.

The Aviation Museum occupies two large rooms in the south wing of the building, while another room is allocated for the memorial room of the Ukrainian kobza player Perepelyuk.
