On the City of Anderida,or Andredesceaster

The Duke of Cornwall's palace at Lostwithiel was built towards the end of the thirteenth century as the administrative centre of the Duchy. It also served for the tin ‘coinage’ and as the meeting place of the County Court. It consisted of a large ‘Great Hall’ together with a smaller hall and buildings for the assaying and weighing of tin. This complex of buildings was never a ducal residence. It became ruinous in the seventeenth century, and much of it was demolished. A fragment of the Great Hall survives, though the smaller, or Convocation Hall, drastically rebuilt in the nineteenth century, is still in use.
