The Kossovo Castle has been dubbed “knights’ dream” for its fairytale-like appearance and splendor. For several centuries it was owned by distinguished dynasties: the Khreptovichs, Sanguszkos, Flemmings, Czartoryskis, and Sapiehas. The golden age of the estate coincided with the years when it was owned by the wealthy industrialist Count Wandalin Puslowski, who was the first in Belarus to use a steam engine. The Kossovo Palace became popular due to its luxurious halls and a magnificent park with over 150 species of exotic plants. The palace boasted over 100 rooms. The Ceremonial Chamber was probably the most amazing one. They say that its floor was made of glass with a fish aquarium underneath.
