Amsterdam floods with orange patriotism as Netherlands new king prepares to ascend the throne

The streets of Amsterdam are awash in the color orange in honor of the Netherlands' ruling House of Oranje-Nassau, as officials prepare for a once-in-a-generation rotation of royal titles — and the rest of the country gets ready to party.

National broadcaster NOS reported that Crown Prince Willem-Alexander and his family were in the Royal Palace on the city's central Dam square Monday morning, rehearsing protocols for the ceremonies Tuesday. Queen Beatrix is to abdicate, Willem-Alexander become king, and his 9-year-old daughter Princess Catharina-Amalia become crown princess.

In the historic city center, vendors are hawking orange clothes; shopkeepers are hanging up orange flags and rolling in countless kegs of beer; while city workers are busy cleaning the streets and canals and setting up bright orange temporary urinals.
