The Guggenheim Museum in Bilbao was designed by Frank Gehry of California and is considered by many to be an architectural masterpiece. It looks just as odd from above as it does from the ground.

Inside Beijing, lies the Forbidden City, the location of the Imperial Palace during the Ming and Qing Dynasties. It is the world’s largest palace and features a six meter deep moat, a ten meter high wall, five halls, seventeen palaces and 800 buildings with a total 9,999.5 rooms. Quite big then.

Tiananmen Square is just to the south of the Forbidden City and lies between two gates, the Tian’anmen to the north and the Qianmen to the south. This is of course the location of the Tiananmen Square protests of 1989 where hundreds of pro-democracy demonstrators were massacred.

The black splodges all over the Forbidden City and Tiananmen Square are the thousands or tourists who visit each day.

The Colosseum (or Coliseum) was built in 72 AD and is 160 ft high with 80 entrances. It held more than 50,000 spectators and was actively used for gladiator fights for 400 years.

The Colosseum obviously featured in Ridley Scott’s Gladiator, although was digitally recreated to its former glory.

Thanks: A whole heap of people called things like John, Jason, Ben, Paul & Jeff

The Millennium Dome is a large dome on the Greenwich peninsula in the Docklands area of London. The dome was built to house a millennium celebration “exhibition” that featured the almost-stolen De Beers Millennium Star diamond and a bunch of other stuff that required a large amount of queuing (from my memory, at least).

The City Hall of Toronto has two towers of different heights, each a semicircle that from above looks a lot like a boomerang. You may also recognise the building as the headquarters of the Umbrella corporation in the film Resident Evil: Apocalypse.
