Description

TAVISTOCK HAMLETS SX 47 SE 6/9 North portal to the tavistock Canal tunnel at NGR 460 723

GV II

North portal to the Tavistock Canal tunnel. Dated 1803. The Tavistock Canal was built 1803-17 by John Taylor. Slatestone rubble will limestone datestone. The Tavistock Canal connected the Tavy to the Tamar over a distance of 4½ miles. For nearly 2 miles it runs in a tunnel under Morwell Down. The north portal has a lock to one side to regulate the water flow. The portal is cut into the rock face, and has a round arch with voussoirs and keystone, with large datestone over. The rubble walling rises about 3 metres above the archway, with coping. The south portal at Morwellham (q.v.) is of the same design. (Sources: Booker, F.: Industrial Archaeology of the Tamar Valley.
