Spoffy, thanks very much for directing us to Wikipedia. i spent ages trawling through various tourist pages on the location and found nothing of help except possibly a church, which could have been revealed by changes to row 5.
I agree with malone that it's a bit of a stretch to call one of the items a landmark. I also think it's unreasonable to have doubly hidden items without giving solvers additional information, such as length, or symmetrical relationship, or the fact that they occupy two pairs of entries.
Finally, where is ANDY LEMON? Perhaps I have a wrong entry, but all I can see is ANDCY LEMON. Doesn't seem very satisfactory to me, but if I have screwed up on my grid then apologies to the setter.
