By size · Order from shortest to longest.

1. A blue whale 28 m

   The largest animal ever known, its heart alone is the size of a small car and beats just a few times a minute.

2. A tower of the Golden Gate Bridge 227 m

   The bridge's 'International Orange' colour was chosen partly because it stays visible in San Francisco's thick fog.

   Mythical home of the Greek gods, its peak was not officially climbed by humans until 1913.

   It was once so polluted that 1858's 'Great Stink' forced Parliament to finally build London's sewers.

   One of the world's longest national roads, it stretches across six time zones from the Atlantic to the Pacific.
