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

The Hreptovich estate in Shchorsy is a partially preserved 18th-century palace and park complex. Its palace, built 1770–1776 to a design by Giuseppe de Sacco, was a one-storey rectangular block with a two-storey central cross wing under an oval cupola; it was demolished in the 1950s. The library building, the west wing, the red-brick smokehouse and the vaulted cellars survive.

The estate belonged to the Chreptowicz family from 1471, when Lithuanian records already name it as theirs. In 1770–1776 Joachim Chreptowicz, deputy chancellor of Lithuania, had the palace built to a design by Giuseppe de Sacco, with interiors by Carlo Spampani and construction led by E. Gabriel. The palace was damaged in World War I and demolished to its foundations in the 1950s.

The estate's library, founded by Joachim Chreptowicz, held up to 8,000 volumes, later expanded to 15,000 by his sons Józef and Adam. The poets Adam Mickiewicz and Jan Czeczot, who worked there as librarian, used it, as did astronomers and historians such as Marcin Poczobutt-Odlanicki and Joachim Lelewel. The Latin inscription PACI ET LIBERTATI (Peace and Freedom) was added to the palace pediment in the second half of the 19th century.

The estate lies on the north-western edge of Ščorsy, about 1 km east of the red-brick Murawanka farmyard with its round corner towers. The library building, used as a school until 1982, and the western wing survive; the palace itself is only vaulted cellars and foundations. The landscape park of about 40 ha is overgrown and partly waterlogged, so wear suitable footwear.

The palace held a library of up to 8,000 volumes, expanded by Joachim Chreptowicz's sons Józef and Adam to 15,000 in the first quarter of the 19th century. The astronomer Marcin Poczobutt-Odlanicki and the poets Adam Mickiewicz and Jan Czeczot worked there, the latter as librarian. A two-storey classicist library building was erected for it in the late 18th century.
