The flag parade (of the Rotterdam Flag Parade Foundation) is an 'outdoor museum' with 230 flags next to each other at one of the most beautiful and busiest locations in Rotterdam, the Boompjes boulevard on the Nieuwe Maas, between the monument De Boeg and the foot of the Erasmus Bridge .
There are 193 country flags to welcome the 193 nationalities living in Rotterdam or visiting that city/port – as represented in the United Nations. There is a flag for everyone who lives, works or visits the city in Rotterdam. The other flags (poles) are reserved for Rotterdam municipal flags. The flag parade is made possible in part by financial support from the municipality, contributions from founding members and initially also sponsors and now from a charity foundation.
