The Thames barrier was built, because of the Thames flood in 1928. The Thames river flooding destroyed lots of properties and 14 people lost their lives in the flood. So, the Environmental Agency came up with the idea of the Thames Barrier and its construction started in 1974. It is predicted that even with heavy rainfall and rising tides due to climate change it will still be able to protect London from flooding until 2070.

Lunar Eclipse 2018 - Fun Facts
