La mine de Plombières

Parking disc 30 min, but Saturday after 12:30 and Sunday free parking. Good starting point for walk.

Plombières (Bleyberg) owes its development to the mine during the 19th century.
Before that, Bleyberg was just a small hamlet between other towns. It is not known when you started mining ore, but the first entries are from the mid-14th century.
