Toolse is a village in Haljala Parish, Lääne-Viru County, in northeastern Estonia.[1]
Toolse castle (German: Tolsburg) was a crusader castle belonging to the Teutonic Order. It was completed in 1471. At one point of time, it was reportedly the northernmost outpost of the Holy Roman Empire.[2]
Today only ruins remain. A conservation and archaeological survey scheme has been carried out at the site since 2006.[3]
