Welkom en welkom gefeliciteerd in deez' wonderschone hoofdstad van ons land! Congratulations! You live in the real and formal capital of the Netherlands. The Dutch government has its seat in The Hague (Den Haag, 's-Gravenhage).

Which makes it the capital by both the English meaning of the word (Webster) and the Dutch meaning of the word (van Dale). Note that when I was at school we were taught that The Hague was the capital, while the only claim to fame of Amsterdam was that Kings and Queens would be crowned there.

Forgot to mention something. You talk about "formal capital", but that can only be the case if it is written down somewhere in the legislation, but there is nothing about that anywhere. My (Dutch) encyclopedia (which postdates my schooldays by quite some years) says: "Generally Amsterdam is seen as the capital of the Netherlands although the seat of government is in The Hague." Note that this implies that it is not universal, nor that it would actually be correct. dik
