Postbridge is a hamlet in the heart of Dartmoor, Devon. It is situated on the B3212, between Princetown and Moretonhampstead. Postbridge is situated on the East Dart river, one of two main tributaries of the River Dart, and consists of a few houses, a shop, a public house, and a national park tourist information centre. Postbridge is best known for its 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 stands alongside another bridge, a Grade II listed structure built in the 1780s for the Moretonhampstead to Princetown Turnpike.
