Helsingor, also known by its English name Elsinore, is a city in Helsingor municipality on the northeast coast of the island of Zealand in Denmark. It is known worldwide as the setting of William Shakespeare's Hamlet. The name is taken from Hals meaning "narrow strait" and it referred to the passage between Elsinore and Helsingborg. Helsingor today was founded in the 1420s by the Danish king Eric of Pomerania. He established the Sound Toll in 1429 and built the castle Krogen, which was made larger in the 1580s and named Kronborg. The oldest parts of the cathedral of Elsinore date back to the 1200s, Elsinore was then a town of a meaning. At least, there have always been some form of ferryboats crossing between Elsinore and Helsingborg.
Kronborg Castle is a main tourist attraction. Hamlet has been played a number of times in here. Kronborg attained its current name in 1585 when it was rebuilt by King Frederick II into a superlative renaissance castle distinctive in its appearance and size all over Europe. Kronborg also has a statue of Ogier the Dane, who, slumbers here until the day Denmark is in danger, at which time he will arise and save the nation.
