Joniškėlis Manor Park is a distinctive park, one of most iconic parks in Lithuania, established in the second half of the 18th century and expanded in the 19th century on both sides of the River Mažupė, a tributary of the Mūša. There are three ponds, lime alleys, more than 20 species of native trees and shrubs, and over 30 species and forms of introduced plants. There is a large square in front of the palace. The park is a state protected site of national importance. Joniškėlis manor belonged to the Karpys family from the middle of the 18th century. The palace is now home to the Lithuanian Institute of Agriculture’s testing station and Joniškėlis Regional Museum, which houses books dating back to the period of the ban on Lithuanian printing and the book smugglers.
