left. In front of this the 'plat' (platform) for stacking the tin ore and an ancient

This: building, though much altered, is part of the historically very important
Godolphin tin works. Sir Francis Godolphin was a great innovator in the tin industry
and introduced the process of 'wet stamping' whereby water ran through the ore under
the heads of the stamping mill. The storage pond, leat system and 'buddle pits'
(circular tanks in which the ore was separated from other materials by agitation)
exist as does the 'blowing house' itself (q.v.) This is a site of crucial importance
to industrial archaeology.

site in the 1950's;
