I think you're right.....

What is it called and why is it of interest?

I know because I have been there, will let it run.

I know also but I haven’t been there.

Crusader castle?

I will give a clue, when it was in use you would not want to be there.

It featured in an episode of Abandoned Engineering the other day...

That’s what I’ve seen it on.

Reminded me of this...

.

Is it Spinalonga?
The leper colony island 1903-1957.
Known today as Kalydon, a tourist attraction.

No it isn't Cathy (unless it has two names) but you are so close and these clever Dicks all know what it is. You are right it's a former leper colony and here's the LINK to the wiki article and I see you are right after all, I was calling it the wrong name.
So exactly right Cathy.
Next one?

I knew it from a book I have read called The Island by Victoria Hislop.

We went on a boat trip when we were on holiday in Crete.

Where is it and what is it?

Ooh! I know, it's in that there London. It's the slipway for the Great Western

Strictly speaking Kev, no you're wrong. It was the Great Eastern actually. But you have it right.
Next for shaving? (I am trying.....)

What is it?

A pick for something, it’s very nice, something to do with sewing?

Not sewing Gloria.

Something delicate, watch making perhaps?

Sorry, no. The carrying case is a clue Gloria.

Is it off a housekeeper’s chatelaine? It looks as though it clips onto something.

Non-magnetic bomb disposal tool.

Corset hook

Ear wax broddler, sort of thing you poke in the ear to clear it?
