I remember the Napoli too, went and had a look out of curiosity. Also not heard of this Lego incident! Of course shipwrecks, and even wreckers have an illustrious history down here.
I've visited Branscombe every year of my life - we've a family connection. It used to be a fairly quiet but known seaside location, but ever since Napoli it has been much busier. I assume it's all those people who went and had a look and decided it was a pretty place to visit...

And earlier this year too - cigarettes this time:

I'm lucky enough to live in Cornwall and I'd never heard of the lego thing, very interesting!
