The Burcht van Leiden (Dutch pronunciation: [ˈbʏr(ə)xt fɑn ˈlɛidə(n)];[1] Fort of Leiden) is an old shell keep in Leiden constructed in the 11th century. It is located at the spot where two tributaries of the Rhine come together, the Oude Rijn and the Nieuwe Rijn. The structure is on top of a motte, and is today a public park.
