The place is excellent! The castle and the grounds are very beautiful, the lavender beds create their own special atmosphere. On a hot day, the spray from the fountain is refreshing. There are interesting expositions inside the castle, convenient navigation through the castle. If you decide to visit and book an excursion, then keep in mind that this must be done in advance, since there are many people who want to and the guides are all busy. There is an audio guide and information signs. A single ticket is included in the price and the castle and the museum of T. Kosciuszka. There are souvenir shops, a food court and a cafe nearby. Large parking lot.
What I saw exceeded my expectations!! The Puslovsky Palace is beautiful inside and out! There is an interesting exposition inside - interiors, an exhibition of a 19th century costume, showcases with gizmos from the 18th to the 19th centuries. I especially liked women's haberdashery from the past - fans, perfume bottles, muskets, handbags, lorgnettes. There are stands with comprehensive information in the halls, you can read and explore without a tour. There is a small regular park around the palace with flower beds and a fountain. Nearby is the house museum of the Thaddeus Kosciuszko family, also worth a visit.
Convenient parking, souvenir stalls and toilets are available.
In Kossovo itself there is a beautiful church of the 16th century, active.
I definitely recommend all the historical and tourist sites of Kossovo to visit!
