This is one of the most expressive estates built in the style of Romanticism. Dating back to the 19th century, it is on a peninsula in Astravo, which can easily be reached from Biržu along the longest wooden bridge in Lithuania, crossing Lake Širvenos. Covering 18 ha, the mixed-plan park was installed from 1851 until 1862. Local fir trees, linden trees and pine trees grow in the park.
