Postbridge is a hamlet in the heart of Dartmoor in the English county of Devon. It is situated on the B3212, roughly midway between Princetown and Moretonhampstead.
Postbridge is situated next to the East Dart river, one of two main tributaries of the River Dart, and consists of a few houses, a shop, an inn, and a national park tourist information centre.
However, it is best known for a fine example of an ancient clapper bridge over the river. First recorded in the 14th century, the bridge is believed to have been built in the 13th century to enable pack horses to cross the river, carrying tin to the stannary town of Tavistock. The clapper bridge which is a Grade II* listed structure, is still complete, and stands alongside today's structure, a Grade II listed structure built in the 1780s.
