Royal Palace Amsterdam (Koninklijk Paleis)

The impressive Royal Palace Amsterdam, located on Dam Square, is one of Amsterdam's top attractions. It was built in the Dutch Golden Age as the city hall for Amsterdam. It later became a palace for the royal family, a function it still has to this day. Consequently, it's not always open to the public.
It plays a key role during State visits and it's also home to some pretty amazing 17th-century art - representing the Dutch Golden Age.
