If you think Bristol or Aberdeen are mad then try Norwich: https://www.openstreetmap.org/relation/172506 Again presumably due to Norwich's history as a port and therefore having control of the river. Tom On 12/09/2020 22:53, Russ Garrett wrote: Yeah, I assume what happened is that the City

Yeah, I assume what happened is that the City of Bristol ended up, at some point, as a statutory port authority (which I think they were until 1991), and somehow the boundary from that has remained as their local authority boundary. But it's still a fairly unique situation as there are many other

This anomaly gives rise to the situation that there is a triangle (more or less) of water near Flat Holm which is simultaneously within the jurisdiction of Wales and the City of Bristol. It probably only matters for things like fishing, as that was basically the reason to define clearly the

Oh wait, I remember now. This is correct for extremely stupid reasons relating to the boundaries of the county of Bristol including a large chunk of the Bristol Channel. I can confirm the boundary in OSM matches the one in OS Boundary Line. That relation could probably do with a note tag on it,
