@voyageur: Thank you! But please read the post just above yours.

I cannot and will not integrate corrections manually. It doesn't make sense on auto-generated data!

Please direct your requests directly to UNESCO, they have an open ear, I think.

If you think I analyzed UNESCO's data wrong, let me know.
But In your case, take a look at http://whc.unesco.org/en/list/712/multiple=1&unique_number=712bis , and you will find that the coordinates for Villa Pisani are (as of Aug. 26, '05) exactly where my placemark is.
