Once I'd written The End on the last book (For His Eyes Only - Kiss/Modern Tempted) the dh and I did what we'd been promising ourselves for ages and drove a few miles up to the road to Lacock Abbey and Lacock village.
Lacock Abbey is most famous for being the home of William Henry Fox Talbot, a pioneer in the film of photography but it's a lot older than that. It was built on the foundations of a former nunnery and has amazing cloisters, and medieval rooms on the the lower floor - where three of the Harry Potter movies were filmed - and more recent, Tudor stuff upstairs.
If you're planning on coming to the area (and it's close to Bath), try and take a few hours to visit. There are lots of great places to eat - our local Romantic Novelists' Association Chapter meets every couple of months at The Sign of the Angel.
