Since its creation in year 43 by romans, London did expand quite a bit but the old father Thames did not. Although today it is the one and only river one can see walking in the city of London. Long before, many tributaries of the Thames ran freely among the villages, providing it with fresh water and fish. One of these tributaries, the Tyburn, even has an angling society dedicated to this site. Yes, it  still exists even if the stream is now buried as all the other lost rivers of London to reduce the open sewage city in the growing city and so to mitigate the diseases spreading with it (during the 18th and 19th centuries). Today the Tyburn Angling Society’s main goal is to restore the lost stream by deculverting it and rehabilitate it as the rich ecosystem it used to be in the past. Maybe the plan includes to destroy many old houses including Buckingham palace, but aren’t we ready to give up anything for the possibility to fish salmon around Westminster Abbey ?
