Royal Palace of Amsterdam (Holland)
The classicist palace located on the Dam Square began its life in the 17th century as a city hall. Its construction started in 1648 and the city hall was opened for the first time in 1655. During the reign of Louis Napoleon, it was turned into the royal palace. Nowadays, it is one of the three palaces that belong to the royal family.
If you want to avoid queuing, you can buy your tour tickets online. When entering the palace be prepared for security checks. Bags and purses must be left in the cloakroom before entering the palace.
Also, since it is a royal palace it is closed for public on days when there are some official diplomatic events hosted or on royal family-related days (e.g. weddings, jubilees etc.). Therefore you might want to consult the official website before your visit.
