If you enjoy classical music, you might want to check this out in August. Several canal boats act as a stage in the Princengracht canal for a live concert. A very unusual, but typically Dutch event, it takes place in front of the Pulitzer Hotel. This is part of the much larger Grachtenfestival of diverse music performances on the canals around Amsterdam.
Music lovers jam the surrounding streets and squeeze into the canal itself. The Princengracht becomes blocaded with boats full of partygoers eating and drinking to the accompaniment of wonderful classical music floating across the canal.
