A'dam is the iconic and controversial tall building next to the Eye Film Institute and opposite Central Station. It calls itself "a tower of many talents": you can grab a bite, work in a coworking space, rave at the club and spend the night at the hotel here. The tower hosts some major creative labels, so the crowd is always interesting. For some adrenaline, check out the A'dam Lookout — an observation deck with a panoramic view of Amsterdam, an interactive exhibition and free audio tour about Amsterdam’s history and culture. A swing that lets you dangle your feet off the edge of the building is the cherry on top.

In addition to the Easter- and Summer Festivals, Salzburg has also featured the Whitsun Festival since 1973. In this case, Herbert von Karajan’s original idea was to give those people who had not been able to obtain tickets for the Easter Festival an opportunity to listen to acclaimed international orchestras between Whit Saturday and Whit Monday.
