Where are they going?

I actually passed by this alley and quickly turned the camera back on and went back to take a snap, they were pretty unsteady on their feet, supporting each other over the cobbles. The alley they're heading down is usually blocked by a gate as it belongs to the office. I hope it's open at the other end and they don't have to come all the way back and walk round the block to get to where they're heading.
