This bit of grass is apparently called "Bobby's Green" or "Bobbies Green"—I've seen it written both ways. Several locals call it this; the only guess I've seen came from Louise on NextDoor:
don’t know why it’s called the Bobbies green except sometimes policemen used to lean or leave their bikes on the railings before there were so many parked cars. They used to come up constitution hill from the old police station at the entrance to Brandon hill on Jacobs Wells Rd and cycle around clifton so maybe that’s the reason- but that’s just a random guess.
