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.

This study was commissioned by the landowner on behalf of Natural England as part of a Higher Level Environmental Stewardship Agreement Scheme and produced by Cornwall Archaeological Unit, Cornwall Council.
The Morwelldown tunnel portal (see Fig 26), attempts to create an impressive façade with a granite portal stone and the date stone 1803 in raised letters incised in granite over the tunnel opening. The lintel is approximately 1.2 by 0.8m with two supporting stones. The ground level above the crown of the tunnel is approximately 3.2m high and 5.8m wide. Perhaps of more visual significance is the rock cut channel that has been excavated, approximately 90m long and 5.5m high at its portal end. This was originally faced with stone, but in places has collapsed. The tunnel opening is approximately 2.75 m high from water level to its crown and 1.8m wide at water level.
Significance
High
This site has a High significance rating, given its site history, its impact upon the landscape and its designation as being part of the Cornwall and West Devon World Heritage Site. The tunnel portal and tunnel itself are Listed Buildings (Grade II).
Recommendation
Site should be retained after any obscuring vegetation clearance. If there is to a site interpretation strategy for this higher stewardship scheme, this could include the provision of an interpretation panel, for example near Site 52.1, (near the towpath and overlooking the site of the Wheal Crebor water wheel), a viewpoint perhaps towards Wheal Crebor mine across the Lumburn Valley. The provision of occasional guided tours around Wheal Crebor Mine could also visit this impressive feature.
