There's an island near me, St Mary's Island, that used to be a Royal Navy nuclear submarine fuel dump, or something along those lines. Within the past couple decades though they've cleaned it up and turned it into a (slightly radioactive) housing estate. <br>There's still a lot of historical junk around us though. Clay Pipes from the Napoleonic wars wash up on the rocky beaches all the time. We used to collect them when I was a kid.
