Gargždai Manor is first mentioned in written sources in the first half of the 15th century. In the 15th–16th centuries the manor belonged to the Kęsgaila family, elders of Samogitia, and later to Baron Rönne. The park was established on the slope of the Minija River in the first half of the 19th century by the Rönne barons. It was reconstructed and extended in the mid-20th century. The site consists of a level western terrace and the gentle slope of the Minija bank. From it there are superb views of the Minija winding below. The park is criss-crossed by a network of straight avenues intersecting at right angles, with three curved terrace paths. Extended to the east, the main avenue crosses a rectangular space formed by avenues, which leads to the cemetery of soldiers who died in the Second World War. The main avenue continues as a curved path with groups of steps leading down to the river. Walking along it, picturesque views of the Minija valley open up. On the continuation of the old park's axis, on the other side of the Minija, rises a well-known 13th-century hill fort. The axis of the new park runs along the edge of the Minija bank. Because of its two clearly distinct parts, the park is considered a composite park.
