Wheal Anna Maria Calciner Complex

Highlight • Structure

Wheal Anna Maria – a copper and arsenic mine – covered 3.2 hectares and had over 6,850 cubic metres of arsenic flues!
It was named after the Duchess of Bedford!
Her main workings were on the ‘Main Lode‘ (the largest sulphide deposit in southwest England).


When its rich copper waned, Devon Great Consols became the largest arsenic mine in the world because the margins of the copper-rich lode were dominated by arsenopyrite.

In 1860 the copper lode at Anna Maria was up to 45 feet wide and yielding up to 80 tons per fathom, but by around 1880 the copper boom was over. Thankfully, arsenic production sustained the mine into the 1900s, until the company folded.
Arsenic ore, unlike copper ore, was refined on site using the ‘calcination’ process – and at Wheal Anna Maria they yielded over 72,000 tons of refined arsenic! – Whoop!

Area of coniferous woodland, near Tavistock, situated on the banks of the river Tamar.

The woods are home to plenty of hiking and bike trails, and offer plenty of scope for exploration.

View from Blanchdown Wood

Highlight • Forest

Beautiful views up here from Blanchdown Wood on the Mineral Railway.

Look down and you will see the spoil heaps of the Great Devon Consols, the name of the mine once situated here. First copper and then arsenic was mined here and signs of the long gone industry can be seen throughout Blanchdown Wood.

Horsebridge over the River Tamar

Highlight • Historical Site

Straddling the River Tamar and marking the border or Devon and Cornwall, Horse Bridge, in the hamlet of Horsebridge, was built in 1437. It's one of many similar bridges in the South West and is in particularly good shape, continuing as a road bridge.

Find a pub on the Devon side in the north of the hamlet and enjoy the stunning views of the river from the bridge's refuges.
