>The sea may well have buried it again, but it would still be there where it was intended to be.<

Well, I agree with the rest of your post Peter but not the last line. Unless Seahenge was built by Atlanteans it most certainly wasn't intended to be where it was (under the sea).

Again this is ultimately a question of how to fund appropriate conservation (and not just conservation of the structure but also conservation of the environment into which it was placed). But how do you do that with something like Seahenge where the waves are literally lapping at its doorstep and money is just not available to both <i>see</i> the structure <i>and</i> preserve it? I liked your idea of a damn and I also wonder just how difficult (and how expensive) something like a transparent dome would have been to construct? A dome that would have allowed seawater in when Seahenge was submerged but not out when it was exposed? Perhaps that idea was discussed... perhaps I'm just being fanciful again.
