Such old structures just take me a few centuries back right away! It has so much more atmosphere to it than most modern buildings in my opinion. How old would that bridge be?
I'm afraid I do not know the age of this particular bridge, but I can tell you there are many bridges on Dartmoor that date back to 1380's, they are the old clapper bridges probably built by farmers as they settled on the moors. http://www.fotolibra.com/gallery/658881/dartmoor-postbridge-clapper-bridge/like/
