This is at Wakefied (just an hour's drive).
Visited on Saturday and was deeply affected by the conditions and the hardships of being a miner.
Although my ancesters came from Cornwall to sink pits in Huncoat; in my lifetime, they were more or less employed in the textile industry, so know little about this past industry.
It is an excellent day out, especially if you take the trip to go underground. In fact, will go again as didn't get time to explore all the museum or outside exhibits.
It's all free.
