Yeah - think that podcast is from 2017.
When you are down in that there London, have you ever walked from Embankment tube to say somerset house? Baffles me why it's not made more of but the enginering to reclaim land back from the Thames and the sewage system created by Bazalgette. Thirty odd acres were reclaimed back from parliment to blackfriars.
So the gardens you can walk through today at embankment were all reclaimed prior to this on the banks of the thames were grand houses that went to the old shoreline - of which somerset house is the only one left. Which fries my noodle when you see how set back it is today.
Anyway, I digress, but its something that we should make more of like they do in other european cities but it's just sort of a hidden bit of London history.
