This is Caversham Court in Reading, a former Rectory to nearby St Peter's Church and one of the second grandest houses in the Parish dating back to the early 1800s.
In 1933 it was razed to the ground by Reading Council to make way for a road which was never built.
Thanks to the tireless endeavours of several local citizen's action groups and charities, Caversham Court is now somewhat redeemed as a newly-restored riverside public park, and you can walk around the outline of where the grand house used to stand.
Christchurch Meadow in Oxford, surely one of the most stunning vistas to be found in England and the stuff of Brideshead Revisited with the rivers Thames (aka Isis) and Cherwell bordering two sides of it and Oxford Colleges, the third, not to mention the Botanic Gardens invading a corner, and steeped in about as much history as it's possible to find, including early balloon landings and mediaeval settlements. In the 1950s a city councillor thought it would be a great idea to build a road straight through it. Luckily he didn't get away with it as doughty Oxford citizens fought back.
Makes you wonder what we have lost elsewhere though. What other country is as short-sighted as England so often is about carving up its towns and cities in the name of 'Progress' (but more often mere sacrifice to the greater glory of the combustion engine and its continued sales and movement). And I speak as the possessor of a driving licence who happily uses alternative transport wherever it exists.
