Right in the heart of the city, you can visit the famous Planten un Blomen park where there are stunning fountain shows throughout the day - in particular the one at 2200 which includes a sound and light extravaganza to go along with the water show. The Hamburg Television Tower is one of the tallest buildings in Europe, and for a charge you can go to the observation platform in order to enjoy a panoramic view of Hamburg and its surrounding area. If you're the kind of person who'd rather eat while they watch, there is a revolving restaurant on the level below, which incidentally is one of the most popular places in Germany to propose marriage.
