If you are a Star Wars fan, Cruachan is the location of The Empire’s base in Andor.
As a Scot, who’s done a lot of hillwalking in the past (and been scared witless by airforce jets suddenly appearing over the brim of a hill) it was amazing to see tie-fighters whooshing across the Scottish landscape.
I visited Cruachan in 2019 by happenstance. It is really cool! I'm going to look for the Star Wars tie in - the architecture certainly does fit the theme. You can watch a Pathe video on Royal Opening of the dam and power station here https://www.britishpathe.com/asset/87792/
