The German order built a stone castle here in 1242, and only a few fragments of it remain along with a vaulted cellar in which local wines can be tasted if you register in advance.  The castle of the Duke of Courland was here later, but it was destroyed during the Great Northern War in 1701.  Reconstruction of the park involved wooden pathways and bridges, information stands, a pergola and a fountain.  There are 22 sculptures in the park that are the work of Līvija Razevska.
