Kronborg is known by many also as "Elsinore," the setting for much of William Shakespeare's famous tragedy Hamlet, Prince of Denmark. Kronborg Castle is situated near the town of Elsinore (Danish Helsingør) on the extreme tip of Zealand at the narrowest point of the Oresund (Danish Øresund), the sound between Denmark and Sweden. In this part, the sound is only four kilometres wide, hence the strategic importance of maintaining a fortress at this location. The castle has for centuries been one of the most important Renaissance castles in Northern Europe.
