Kronborg Slot, Helsingør
Kronborg Castle is a UNESCO World Heritage Site as well as the site for Shakespeare's Hamlet. As a result, it is at the top of Helsingor's list of must-see attractions. Even those with only a passing interest in Shakespeare will be compelled to pay a visit. As you approach, the enormous edifice is readily apparent, so you won't be able to miss it.
Although other strongholds before it, the current incarnation dates from 1640. The Kronborg Castle was restored in 1924 after serving as a garrison for a century or more. The Castle Chapel, which survived a fire in 1629 and boasts a spectacular Renaissance interior with German wood sculptures, is located in the South Wing. The grand Ballroom, also known as Knights' Hall, is located in the North Wing, while the West Wing has superb tapestries.
Exploring Kronborg Castle's eerie crypts and catacombs is a fantastic experience. Holger the Dane (Holger Danske), an imposing stone statue, is hidden deep beneath the castle. In Danish culture, Holger the Dane is a mythical person. He'll rise from his granite throne beneath Helsingr and defend Denmark if she's ever in jeopardy!
