Hi Stordfield,
habe mal ein wenig gegoogelt und denke das könnte deine Frage beantworten.
"In 1829, when Sir Robert Peel was Home Secretary, the first Metropolitan Police Act was passed and the Metropolitan Police Force was established in London. The task of organising and designing the "New Police" undertaken at 4 Whitehall Place. The back of this location opened on to a courtyard which, as a popular anecdote would have it, had once been the site of a residence owned by the Kings of Scotland (or, alternatively, a Scottish Embassy), and was therefore known as "Scotland Yard". These headquarters were removed in 1890 to premises on the Victoria Embankment known as "New Scotland Yard." In 1967 further removal took place to a larger and more modern headquarters building at Broadway, S.W.1, which is also known as "New Scotland Yard". "
