Canberra - none. In fact, none of the cities on Australian soil had been conquered before...quite boring if youre looking at it from military point of view...
London:
Founded by Romans.... "conquored" or rather taken over by the Celts before generally absorbed by the Angles and Saxons... then along come those horrible Scandanavians but although they beat it up a bit they never bother to conquor it properly. Then that frog-eating muppet "William the Bastard" (historically accurate name!) comes and calls it home.
Um, that was the last time I think although it sort of changed hands a few times during the "Wars of the Roses" and the English Civil War but never requiring considerable force IIRC.
London was never conquered during the Civil War or War of the Roses - it was occupied without a fight, I think.
For William the Conquerer, the war was over before anyone got near London.
In Roman times, what was called "London" wasn't actually the modern city. Boudica burnt it down, then the next Roman city was just abandonned. A new city was made by the Celts - it was then moved again afterwards.
So you could argue that London (i.e. the current city) has never been conquered.
most of what you are saying is crap
one could argue
I know we can be patriotic
Beijing(Northern capital)
1) captured by Mongols
2) Surrounded in 3/4 directions and then captured when Japan attacked(even though it wasn't the capital of China back then).
Nanjing(Southern capital)
1) captured in 1937
Chongqing and Guangzhou, capital of Nationalist China during the Chinese civil war, conquered by Communists 1949(maybe only getting conquered by foreigners count)...
It was Golle, not me, that said London has never been occupied by foreign forces.
