The palace and park complex Tyzengauz, Postavy, Palace complex in Postavy, Belarus.

Tyzengauz Palace is a classical-style structure featuring symmetrical facades, detailed cornices, and rows of tall windows across multiple levels. The grounds contain a park with canals, ponds, and established tree groves that frame the main building.

In 1686 the estate passed to the Biegański family as the dowry of Apolonia Zenowicz, and in the first half of the 18th century Anna Biegańska's marriage to Benedykt Tyzenhauz brought it to the Tyzenhauz family for over 150 years. For Antoni Tyzenhauz (1733–85), treasurer of the Grand Duchy of Lithuania, a classical palace was built in the second half of the 18th century to a design by the Italian architect Giuseppe de Sacco. An 1788 inventory recorded the side wings finished and the central foundation laid; the building was extended in the early 19th century and took its final form around 1850 under Konstanty Tyzenhauz.

The palace served as a residence for a wealthy landowning family and reflects how regional nobility lived and entertained. The surrounding park with its tree-lined paths shows how estates were designed for both beauty and leisure.

The palace still houses a district hospital department, so the interior is closed to visitors; the basement museum opened in 2014 is the exception. Enter the park from Savetskaya Street at house 73 and walk the surviving alley that once led to the bridge over the Myadelka. The 2006 monument to Konstantin Tyzenhauz stands in front of the facade.

The family who built the palace was known for its interest in science and nature study. One family member became notable for bird research and left substantial contributions to the field of ornithology.
