Following the partitions of the Polish-Lithuanian Commonwealth the town became part of the Russian Empire.In 1850 the estate was bought from Izdebski by Count Józef Tyszkiewicz (1835-1891).
In 1885 he had a Tudor-style palace built on the northern shore of Lake Lentvaris,[5] which was widened during 1850-1873; a causeway connected the estate, which was surrounded on three sides by water, with the town.
Józef also planted a large park next to it, designed by the well-known French landscape architect Édouard André: local and foreign trees (larch, gray walnut, silver and Swedler maples, etc.)
[6] In 1891 Władysław Tyszkiewicz (1865-1936), who inherited the manor, reconstructed the palace, later it acquired the current appearance of English Gothic.
[9] In 2018, the Lentvaris manor house received 673 thousand European Union support for the reconstruction of part of the building.
