This is Paimpont's other face - a village that provides employment as well as a lovely place to live. This is the water bottling plant that pumps water from deep in the forest for sale as the in-house water brand of the InterMarché chain of supermarkets.
If you want to see what this plant looks like in isolation - you can check it out in today's post in my Ocoloy album - http://365project.org/vignouse/ocoloy/2016-05-15 - but here it is in its rural setting.
We're fortunate to live in such a beautiful area and this bottling plant, providing a limited number of permanent jobs, helps us realise that it's a small price to pay for beauty and serenity whilst enabling many to enjoy Paimpont's excellent water.
A lovely rural landscape, you live in a beautiful part of France and as @s4sayer says, the factory is a small price to pay and also provides some employment locally.
