Hermann Castle, also known as the Narva castle or Narva fortress, is a medieval castle in the city of Narva, in northeastern Estonia. The castle was established around 1256, when the area was part of the Danish Realm. The first entirely stone fortifications were built in the beginning of the 14th century. The Livonian branch of the Teutonic Order purchased the castle in August 1346, and owned it for much of its later history.
