Kronborg Slot, Helsingør
Kronborg Castle is not only the setting of Shakespeare's Hamlet, but also a UNESCO World Heritage Site. Consequently it scores top billing on Helsingor's list of must-see sights. Even those with just a passing interest in the bard will surely want to visit. The imposing structure is clearly visible as you approach, so you can't really miss it. The present incarnation dates from 1640, although several other fortresses preceded it. Serving as a garrison for a century or more, the castle was renovated in 1924. In the South Wing, you'll find the Castle Chapel, which survived a fire in 1629 and has a magnificent Renaissance interior with German woodcarvings. The North Wing contains the great Ballroom or Knights' Hall, while exquisite tapestries are displayed in the West Wing.
