North portal to the
tavistock Canal tunnel at
NGR 460 723


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.
