I've always been curious...
Why do they called it "Scotland Yard"?
It's a funny name for a government institution, let alone a law enforcement institution. After moments (years!) of wondering around with no one answer, I've come to realize that Google is only a click away.
this is what Wikipedia has to say:
The name was actually belong to the building where their headquarter is. And the building used to be located in a place called "The Great Scotland Yard", where they signed the agreement to unite England and Scotland under one kingdom.
Oh... that simple.
Anyway, I've gotten so curious that I decided to actually Googled it, 'cuz I've been reading Agatha Christie's works for the 8976th times.
