In 1773 the brother of the King Stanisław August - Michał Poniatowski, then Bishop of Płock and later the primate of Poland, bought the property in Jabłonna with the intention of turning it into an elegant palace-and-park residential complex.

The construction of a three-building complex was proposed: a one-storey palace, which was intended to be the residence of the owner, was to be situated in the middle and flanked on both sides by separate three-storey pavilions.

A scenic English-style park was developed in the 1770s and 1780s, based on the design of architect Szymon Bogumił Zug.

In early November 2022, the palace has hosted Congress of People's Deputies of Russia, a Russian government in exile consisting of former deputies of the Federal Assembly of Russia in exile (such as Gennady Gudkov and Ilya Ponomarev), public figures (such as Andrey Illarionov), journalists, and several Ukrainian and Latvian politicians (such as Emanuelis Zingeris).

The members of this Congress met, both in person and remotely, to discuss declarations in relation to the ongoing Russian invasion of Ukraine and further a post-Putin Russia.
