Jašiūnai Manor is one of the most significant historical sites in Lithuania, with its origins dating back to 1402, when Jašiūnai belonged to the Radziwiłł family—one of the most powerful and wealthiest noble families in Lithuania. In 1811, after the Radziwiłł family fell into financial decline, Ignacy Baliński acquired the estate, which then passed to his son Mykolas after his death. In 1820, after marrying Sofija, the daughter of Professor Andrzej Sniadecki from Vilnius University, Mykolas settled in Jašiūnai with the Sniadecki family, who became well-known throughout Lithuania.
Jašiūnai became even more prominent when Professor Jonas Sniadecki, having resigned from his position as rector, decided to settle there with his niece’s family. With Jonas Sniadecki's initiative and funds, the distinguished late neoclassical-style palace was built between 1824 and 1828, designed
by a professor of architecture at Vilnius University. The palace stands out with its grandeur and architectural style.
In addition to the palace, the estate features other valuable buildings, such as the office, which was started in the neoclassical style and later expanded during the historicism period, and the stables with living quarters for the gardener, forester, and coachman on the second floor. Near the stables stands a folk architecture building—a barn.
Jašiūnai became an important cultural center, home to and visited by many notable people. The Baliński family also promoted industrial development, establishing sawmills, a turpentine factory, and later building a blacksmith's forge and a copper foundry. After Mykolas Baliński's death, the estate was inherited by his son Konstantinas, and the last owners of the manor were Aleksandras and Ana Peresvet-Soltanai.
