BELPER'S Strutt's North Mill is holding taster sessions for groups of visitors to promote its tours.
The grade one listed building dates back to 1804 and is central to the story of industry and workers' history in the Derwent Valley.
Schools and other organisations are invited along this week and next week.
Museum manager Debbie Richards said: "As well as the innovative fireproof architecture of the building, our museum has period machinery related to the early cotton-spinning industry."
The sessions take place on Wednesday and Thursday this week and on Wednesday and Thursday next week, from 7pm to 8.30pm.
