There are no benches!!!!

A day in Oxford today.
Here we are standing outside the 'famous round building'!! (Radcliffe Camera) wondering where the benches are!!!
In the series 'Endeavour', Thursday and Morse (or is it Lewis and Hathaway?) always sit down on the benches round the railings outside this building to eat their sandwiches.....but the are no benches!!!!!
A mystery!!!
