Šaukėnai Manor is mentioned in written sources as early as the 15th century, when it was owned by the Šemetos. The manor has also been owned by the Jelenskis and for a long time by the Gorskis. In 1931, it briefly housed an agricultural school. Later, it became the Šaukėnai Tuberculosis Sanatorium, and after some time, a psychiatric hospital.
Šaukėnai Park was established in the early 19th century by the noble Gorski family. It was renowned for its oak alleys, ponds, and the swans that lived there. Most of the park lies outside the hospital grounds.
The park is of mixed design
with dominant landscape park elements. On the southern edge, near the garden, on a rise, stands the manor house. To the east of the house is a separate parterre with a loop for access from the east and north. Alleys of small-leaved lindens and common oaks, typical of geometric parks, have been preserved.
In the landscape part of the park, there is one larger and two smaller ponds. An observation mound and a round green gazebo are also present. Among the exotic trees in the park are European larches (height 22–26 m, diameter 52–84 cm), old large-leaved lindens, and western thujas.
