No sorry folks.

I'm uniquely shaped for my type.

It is feet Vince not metres, I did double check just in case  

No it's not Roseberry Topping John.

I was built in the 2nd century AD. 

That's the one John, doesn't matter that you looked it up. It is unique in that it is lozenge shaped, all other Roman Forts are playing card shaped. It's also the highest in the country.

Well done, your turn  

Sorry John, been a bit busy and didn't notice you'd posted this.

I seem to think Flavius was bumped off at the Roman Fort in Ambleside. Where I shall be on Monday  

Here at last 

I was built between 1667 and 1694.

I became a UNESCO World Heritage Site in 1996. 

What am I and where am I ? 

Have you been watching Great Canal Journeys ? Because you are spot on, well done John, I did hope it might last a little longer 

Your turn
