Behind Trinity College, Cambridge University. Many such spaces are out of bounds to the public or available only during certain hours, but Scholars' Lawn on the River Cam seems to be open to the public – perhaps when the gates on Garrett Hostel Lane are open, just next to the bridge.
We went for a stroll around a pleasantly uncrowded Cambridge. It's a beautiful city, lovelier than Oxford in my view, but then the latter is so horribly set about with busy roads.
I had hoped to visit John Lewis for the sale to buy a Sonos Beam sound bar, but it was shut – rightly so.
