The Tyburn Angling Society purports to have been established by a royal charter issued by King Edgar the Peaceable in 959 AD, though there are no records of its existing before the 21st century. The River Tyburn, culverted in 1750, still flows underground from Hampstead to Westminster. The society claims to want to ‘daylight’ the river, bringing it back up to the surface. It commissioned a map in the early 2000s showing the proposed course, which would cut a swathe through ‘£1 billion worth of property’. The buildings marked for demolition included Buckingham Palace and the offices of Westminster City Council, which promptly rejected the proposal.
