One Canada Square is an office building located in London, England. When it was completed in 1991 it became the tallest building in the United Kingdom, a position it held until it was overtaken by the Shard in 2011.
175 years after people: One Canada Square is a shell of what it once was. All of its windows have blown out and the building's steel frame is rusted and weaked. The 11 ton steel pyramid on top of the building is now placing tremendous stress on the weakened frame. Finally the weight of the pyramid becomes too much for the steel fram to bear and One Canada Square collapses.
