I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
There is lots to photograph here: Manchester Cathedral, the Corn Exchange, National Football Museum, Victoria Station, etc.
I flew from the pedestrianised area just north-east of the Cathedral, on a suitably quiet day.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 25/12/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
