Lacock Abbey is the country home of Henry Fox Talbot, and so it’s only fitting that it is the backdrop for many films – ranging from Harry Potter to Pride and Prejudice. Why, you may ask? He’s the inventor of photographic negatives – modern photography – without which there’d be no films. By the way, if you’re in Reading have a look for the house where the first commercial photofinisher shop was located. (It’s near the Sally Ann and not in the best part of town.)
The Abbey is a National Trust property to the south of Chippenham and well worth the visit if you’re in the area. I wouldn’t necessarily drive out from London just to see it as a tourist, but if you’re puttering around the Bath, Chippenham or Bristol, it’s worth a look. You have to pay to visit the Abbey itself or the Talbot museum, but last time I visited the parking was free and you could wander around the village.
