Could I use the word?

Chose a bad title (evrb thinks it's publicity. :) ) and have to repeat my question.
Please,
Would it be wrong to say
<There are a lot of curiosities in Britain.>
meaning there are a lot of interesting things for tourists?

I think "a lot" implies singular so "there is" would be the correct way.

I'd say:

"There is a lot of" or "there are lots of" no matter what the lot/lots contain.

Unless this could be one of those tricky things of language.

No, it would have to be 'there are a lot of curiosities'.

There are alot of curiosities..........or............There are lots of Curiosities.

Tnx, folks,
But my question is :
Is it correct to use "curiosities" in this context, in this phrase; could it be a synonym for "interesting things"?

No. Curiosities does not work in this context. You would have to use interesting things.
