Bremridge is a historic estate within the former hundred of South Molton in Devon, England. It is now within the parish of Filleigh but was formerly in that of South Molton. It is situated 8 miles north-west of South Molton. Since the construction of the nearby A361 North Devon Link Road direct access has been cut off from Bremridge to Filleigh and South Molton. The surviving wing of the mansion house built in 1654 is a Grade II* listed building. Bremridge Wood is the site of an Iron Age enclosure or hill fort, the earthwork of which is situated on a hillside forming a promontory above the River Bray. In Bremridge Wood survives a disused tunnel of the former Great Western Railway line between South Molton and Barnstaple, much of the course of which has been used for the A361. The tunnel is 319 yards long and was identified as "Bremridge Tunnel" in the 1889 Ordnance Survey map but as "Castle Hill Tunnel" in subsequent editions.
