Ooh, The Lizard, eh? Lucky swine! ;o)

How about:
<a href="http://www.themodernantiquarian.com/site/234">Halligye Fogou</a>
<a href="http://www.themodernantiquarian.com/site/704">Tolven Holed Stone</a>
<a href="http://www.themodernantiquarian.com/site/3954">Mabe Church</a>

I've not spent much time around that area - I'm sure someone else can give you more ideas than me! There's a number of holy wells down on t'Lizard too...

Enjoy!
