Valsassina was dug for centuries. Through its mountains run kilometers-long tunnels once used to extract various types of minerals , a very important source for the industrial development of Lecco.
Nowadays it is possible to rediscover this ancient mining activity in the mines open to visitors.
In August 2015 Cortabbio Mining Park in Primaluna opened to visitors the Nuovo Ribasso gallery. Originally built in 1980 – 1985 , the gallery leads , through a 2 km course , to a majestic cave where in the last 30 years Baryte was drew.
Guided tours of the mines are conducted in small groups , at all safe conditions and wearing a protective helmet. The underground world seems to be still intact and the well trained guides explain the secrets of extraction techniques and those of miners’ life. The mines are an ideal destination for group visits of students and parishes.
