I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
There's a car park at the Brassknocker Basin. I took off from the field above the aqueduct, about 100m away.
Completed in 1810 by John Rennie, the spectacular Dundas Aqueduct carries the Kennet & Avon Canal over the River Avon and is a Scheduled Ancient Monument. That means it's as important as Stonehenge! In fact, it was the first canal structure to be designated as a Scheduled Ancient Monument in 1951.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 04/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
