In the 17th and 18th centuries, the first Vainežeris Manor House was built on the eastern shore of Lake Vainežeris. A park, two gardens and a nursery were built nearby. In the 19th century, the manor was owned by the Ablamavičiai and Murauskai families. In 1831, a captain, a participant of the uprising, Countess E. Pliaterytė died in this manor. At that time, when the rebels were retreating to Poland, Emilia, who fell ill, was nursed at Justinavas Manor, but unfortunately, she died as a result of illness and grief. A kneeling sculpture (sculptor E. Pauza) has been erected near the remains of the manor house in her memory.
