SEA LIFE London Aquarium

This guide to SEA LIFE London Aquarium starts with the building's old life as County Hall, seat of the Greater London Council, and one of its cheekiest political showdowns: leader Ken Livingstone hanging an unemployment counter in view of Parliament in the early 1980s. You'll hear how Margaret Thatcher responded, and how the corridors of power sat empty for over a decade before reef tanks and circling sharks moved in. Look up at the old council chambers as you walk through, you're standing where London once governed itself.
