We came to Kronborg in January 2016 by train from Copenhagen and spent a night in this small, quiet city. The castle being the supposed setting of Hamlet, the gift shop sells novelty Yorick skulls. It was cold enough that seawater had frozen to the rocks, making for a picturesque view (and to answer Ian Cade's musing, you can indeed see Sweden).
Inside the castle it was fairly typical of European palaces, though not as impressive as sites such as Brühl, Würzburg or Blenheim. There were plenty of local paintings on the walls and some mocked-up royal bedchambers, but overall it was quite bare, with no ‘knockout’ ceiling frescoes or the like. The chapel was nice, but difficult to photograph internally.
A good idea of somebody’s was to put photographs of the famous actors who have played Hamlet at Kronborg in what has become a well-established annual tradition.
