Great historic place! General Seimas of the First Polish-Lithuanian Commonwealth passed here.

In this building, during the last Sejm of the Polish-Lithuanian Commonwealth in 1793, an agreement was signed on dividing the Polish-Lithuanian Commonwealth with Russia and Prussia, and in 1795 the Polish King and Grand Duke of Lithuania Stanislav Avgust Ponyatovsky signed the act of renunciation. The king lived in it until 1797.

In one part of the palace were the royal chambers, in the other - the premises intended for the meetings of the Sejm. For the needs of the Seym, in 1726, a special building was constructed. After 1750, a dome-covered chapel was built, and the entrance gate was also partially preserved. After the division of the Polish-Lithuanian Commonwealth, the Russian authorities staged a hospital and barracks in the palace.
