The Radziwill Manor in the village of Polonechka is an architectural monument in the style of classicism, which was started at the end of the 18th and beginning of the 19th century by the order of Matei Radziwill (famous composer and playwright, author of the opera “Agatka, or Arrival of the Pan”). For a model of the palace was taken Villa Trivulzino on Lake Coma in Italy.
With its first owner, the estate in Polonechka becomes a cultural center, to which celebrities of that time liked to come. For example, there was a Russian writer and playwright D.I. Fonvizin.
During the sections of Polish-Lithuanian Commonwealth, when the Radziwill family estate became the property of the army of the Grand Duchy of Lithuania, this place lost its former significance and fame. The second flourishing of Polonechka was received when Constantine Radziwill became the owner of the manor. By his order, the palace was heavily modified and acquired distinctive features of the Empire style.
The palace was surrounded by a park that was divided into regular (French) and landscape (English). Feature of the first part of the park were originally trimmed trees and shrubs. And the landscape included four terraces, which descended to the bank of the river. Before the palace, a sundial was installed, and the central alley led to a wooden chapel-tomb.
To the two-storeyed palace on one side adjoin one-story wings. The front entrance is decorated with tetrahedral columns (herms), at the top of which there are sculptural images of the head of the ancient Greek hero (partially preserved) or the philosopher.
In the 20th century, a boarding school was located here for a long time, at this time the building is empty and is in a dilapidated state. Nearby is the Church of St. George, erected in the 18th century, as well as the ruins of a water mill in 1819.
