Toolse Order Castle is one of the more recent medieval castles on the northern coast of Estonia. It is also a castle located closest to the sea. The initial fortified manor house was probably erected by the order in the 14th century with the purpose of protecting the port, trade location and routes. During the Livonian War, the castle passed on through many hands and finally ended up in the possession of the Swedish troops. It was entirely destroyed in the Great Northern War at the beginning of the 18th century.
