Leiden Castle is one of the oldest surviving examples of a castle in the Netherlands. The Castle stands on a motte, an artificial hill, and was part of a so-called motte castle. Archaeologists discovered that the hill must have been built in the late ninth century. On top of the hill was a round wall and a tower, now gone. The Burcht lost its military function as early as the fourteenth century. This beautiful place is a must see when visiting Leiden. When you have walked the many steps, a beautiful view of the city awaits you.
