This UNESCO cover from Denmark depicts a stamp issued in 2020 (from a set of 5) celebrating the
Kronborg Castle. Kronborg is a castle and stronghold in the town of Helsingør, Denmark. Immortalized as Elsinore in William Shakespeare's play Hamlet, Kronborg is one of the most important Renaissance castles in Northern Europe and was inscribed on the UNESCO's World Heritage List in 2000.The castle is situated on the extreme northeastern tip of the island of Zealand at the narrowest point of the Øresund, the sound between present Denmark and the provinces of present Sweden that were also Danish at the time the castle was built. In this part, the sound is only 4 kilometres wide, hence the strategic importance of maintaining a coastal fortification at this location commanding one of the few outlets of the Baltic Sea.
