A: Plenty.
Introducing Amsterdam: the capital Netherlands, the country's most populous city, its cultural hub and probably the most popular tourist & transit destination. Known around the world for the lenient drug (and various other) policies, the canals, clogs, tulips, windmills and a history of commerce, Netherlands is one tiny European giant. Tiny? The country is smaller than the island state of Dominican Republic and its famous capital has a mere population of about 800.000 - that is one tenth of London, one third of Paris and even slightly less than in Stockholm.
The name Amsterdam comes from Amstelredamme, as in "dam of the river Amstel". Historically the city was one the most important ports in the entire world (in the 1600s) and the global center of commerce. No wonder you find Amsterdam sights also on the UNESCO World Heritage List. But enough about the history..
