[1] This building was part of a very large complex, covering more than 2 acres (8,100 m2), built by Edmund, 2nd Earl of Cornwall in around 1280 during the reign of King Edward I.

[4] Henry VII restored the stannaries in return for a payment from the tin miners of the, at the time, enormous sum of £1,000, to support his war on Scotland.

"[6] In August 1644, the English Civil War was at its height and the town of Lostwithiel was taken by Robert Devereux, 3rd Earl of Essex who made it his headquarters.

[1] After the last tinners' parliament was held in the town in 1751,[8][9] the building slowly fell into decay and was sold to the local freemasons lodge in 1878.

[10] Following refurbishment by contractors Carrek, to a design by Purcell, Miller Tritton, the building was re-opened by the Duke and Duchess of Cornwall on 17 July 2013.
