The Ungurmuiža park is well known for its outstanding and huge oak trees. Some of them are rotting or dead, and they are home to a great many species, including many that are found nowhere else in Europe. A pathway leads through these noble trees – 1.3km in length, with visitors spending as much as an hour there. The park also contains the only wooden castle from the early 18th century that has been preserved to the present day. There are other cultural and historical treasures, as well.
