100 years after people. The ground becomes marshy and the basement floods out.
290 years after people. Tower 290 has been weakened from 290 years of neglect but it is still standing, but now a tornado hits London. As it passes by Tower 290 the wind from the twister causes one of the skyscraper's pilings to break. With no piling to stand on the pyramid-shaped skyscraper topples over.
