The Jonava region has long been known for its manors and notable figures. The famous Kosakovski family resided here, the village of Skaruliai is likely named after the noble Skorulskis who owned the local manor, and 16th-century scholar Abraomas Kulvietis hailed from nearby Kulva. Additionally, the region is the birthplace of renowned architect Vaclovas Michnevičius.
Among the preserved estates, the Žeimiai Manor holds a special place. Its history dates back to the late 15th century. In the 16th century, the estate was owned by the Zavišas, Medekšas, and Čechovičiai families. In the early 18th century, Domininkas Medekša, a significant political figure of the Grand Duchy of Lithuania, inherited the manor and initiated the construction of brick structures within the estate. A chapel from this period,
built in memory of Bar Confederation member Teodoras Medekša, still stands.
In 1780, the manor was purchased by Bishop Juozapas Kazimieras Kosakovskis, and it remained in the Kosakovski family until World War II. During the mid-19th century, the manor was reconstructed in the Classical style and underwent another renovation in the early 20th century. After its nationalization in 1941, the manor served various purposes, including housing apartments, an agricultural technical school, classrooms, and even a sewing workshop.
Today, the manor estate is owned by artist Domas Noreika, who has transformed it into the Aikas Žado Laboratory—a unique cultural space hosting art exhibitions, installations, and events. It is not only a historic site but also a modern cultural hub in the Jonava region.
