Today's Geo Quiz takes us right up to the edge of the North Sea.

The sprawling Dutch city were looking for lies below sea level so it was built mostly behind dikes. It's a bustling port, once the world's busiest, until it was eclipsed by Singapore and Shanghai. It still ranks as Europe's largest port and as the Netherland's second largest city.

Boats are common sights along the Nieuwe Maas river that cuts the city in half. They cruise past some of the city's architectural gems including: the soaring Montevideo skyscraper and the gracefully bending Erasmus Bridge nicknamed "the Swan".

Another highlight among the city's landmarks is a tiny fast food shop that sells "patat" otherwise known as salty spuds, starchy strips or better yet ... french fries. Call them you whatever you like...it's the NAME OF THE CITY you have to get just right!

By the way the city's name goes back to its days as a settlement near a dam in a small river called the Rotte.
