Post by Jarle Hammen Knudsen Is this in London? If so, where? https://goo.gl/photos/FmZKU7zbA5u9hTEe8 It's from Lovejoy series 3, episode 10, first broadcast in 1992.
Primrose Hill, at a guess. https://en.m.wikipedia.org/wiki/Primrose_Hill
No guess, Primrose Hill
Thanks, everyone! So it's the BT Tower on the horizon. I notice there's no geocaches there. Is Primrose Hill part of the royal park? For some reason The Royal Parks has decided not to allow geocaches in their parks.
