Emperor Napoleon I of France, received the city keys of Amsterdam.
He declared the city as capital of The Netherlands.
Amsterdam was constitutional mentioned as capital of The Netherlands
due to a change in constitution in 1983.
For me it is always a bit strange because the seat of the government
and the parliament are located in The Hague.
Amsterdam also isn't the capital of its Province, North Holland,
which is Haarlem.
But it really is a lovely city to visit with a lot of famous landmarks.
