SO much potential, but...
First of all, yes, of course, there's a guide. But ZERO options for any language other than German, as there is ONLY the guide; no radio devices.
Second, and this might be more a me thing, but I couldn't care less about the royal family, who slept with whom, which Machiavellian freak managed marry his daughters off so that they had Spain, and on and on and on. I'm visiting a MINE. Required history classes can be taught in a comfortable room; no need to be in a mine for that. In addition, page after page after page of this queen or that prince is shown... poorly. Each image a page in a plastic-sleeve binder, and the guide uses his headlamp to illuminate it. Which causes such a reflection that the image can't be seen, anyway. I mean, FFS, MATTE sleeves, at least.
Even being able to understand every word from the well-spoken (and clearly loving his job) guide, I was bored to tears.
The talk about the actual miners, techniques and technology were minimal.
I'd much rather have heard about what the actual people who WORKED in the mine went through, not about the lives of those who owned it.
What did they do so that dripping water didn't drench them within one hour of starting work? Lanolin-impregnated flannel? Oilcloth?
I'm pretty sure waterproof boots weren't a thing then either. How did they avoid trenchfoot? A mannequin of a boy working equipment was the ONLY indication of child labor, as that went COMPLETELY unmentioned.
How about women? Did any of them work in the mines? If not, and they were 'stay at home' wives, I'm quite certain they weren't spending their days shopping or watching the soaps. How were the lives of these women? Did miners earn relatively well, such that their wives were somewhat better off than most? Or were their lives as much of a brutal toil as the miners'?
That, I believe, would be more interesting to most, than to hear about how a royal-to-royal hit job cost more than what 1000 miners would earn in a year.
Additionally, if you have kids, you might seriously consider skipping Silberbergwerk, as they'll likely be bored out of their minds (and, consequently, make YOUR enjoyment of the mine secondary to promising the kids it'll be over soon. OTOH, they'll love the train ride back out.) read more
