Zorzone (Zùrzù in Bergamo dialect) is the northernmost settlement of the municipality of Oltre il Colle: a shelf of meadows at the foot of Cima di Menna, with the Parina stream flowing below and giving its name to Val Parina. The houses huddle around the church; at the 2021 census there were 193 residents, in 86 households. Sources disagree on the elevation: ISTAT and the maps give 1,016 metres, CAI Bergamo 1,019 for the start of its trails, the Pro Loco 1,100 and the old provincial tourism portal 1,050, differences that depend on the point taken as reference in a settlement that is all on a slope.
Zorzone is the place where the mining history of the basin can be touched. Above the village, towards Val Vedra, opened the mine considered the main zinc mine of the Orobie, with the Malanotte and Pian di Bracca workings. Calamine, sphalerite and galena were extracted, yielding zinc, lead and small quantities of silver, and the complex was not isolated: according to a reconstruction published by Prima Bergamo, a 340-metre shaft and a 12-kilometre tunnel linked Pian di Bracca to the Gorno workings, on the other side of the mountain in the Seriana valley. The mines closed for good in 1982 and the tunnels cannot be visited.
That memory is gathered in the Museum of Minerals and Mining, which the Pro Loco calls the «Franco Palazzi» Museum of Mining and Minerals. It is housed in via Funivia, in the former primary school building, and opened in 1994, although a collection had existed since 1970 in a private room. It occupies three floors: on the ground floor the mining section, with panels, tools and a life-size reconstruction of a tunnel entrance; on the first floor about 500 local finds, 1,600 minerals from all over the world and 450 fossils; on the second the multimedia area with the meeting room and the Lady Irene Memorial, dedicated to the crew of the B24 bomber that crashed in 1944 on the Pezzadello, just below the Menna ridge.
The parish church is dedicated to the Holy Trinity, patron of the hamlet. Zorzone obtained its parish on 24 September 1636 by decree of bishop Luigi Grimani and the building of that time was consecrated on 21 June 1644; the church you see today is the rebuilding begun in 1745 to a design by Giovan Battista Caniana and completed in the following decade, with the 1795 altar made by the Palazzi family and the evangelists painted on the pendentives of the dome by Umberto Marigliani in 1911.
For walkers, Zorzone is a real starting point and not a place you pass through. From here CAI trail 234 climbs through Val Carnera to the MAGA bivouac and Cima di Menna (2,299 m according to the CAI); trail 231 climbs Val Vedra to the Passo Branchino; trail 259 descends Val Parina, a special area of conservation in the Natura 2000 network, down to the Brembo. In the hamlet services are reduced to the essentials, a grocery with a tobacconist's counter and the museum; for the pharmacy, petrol station and offices you go down to the main village, less than five kilometres away.
History
Zorzone grew with its mines. The first communities of the upper Val Serina are perhaps linked to the extraction of iron and zinc on the slopes of the Menna and Arera, according to the municipality's historical record on Lombardia Beni Culturali, and in the sixteenth century Zorzone was one of the five colonnelli (districts) into which the municipality of Oltre il Colle was divided, together with San Bartolomeo, Valpiana, Zambla Alta and Zambla Bassa. On 24 September 1636 the church of the Holy Trinity was made an independent parish, and in 1659 bishop Gregorio Barbarigo found it run by the villagers, who paid their own curate. In April 1797, under the Bergamo Republic, Zorzone became an independent municipality, with a district matching the parish, but by March 1798 it had been reabsorbed by Oltre il Colle.
The zinc epic began in the nineteenth century. Extraction between Gorno and Oltre il Colle started under companies such as Aurera and Sileoni; around 1850 the Italian companies were taken over by the English Crown Spelter and the Belgian Vieille Montagne, and in 1919 the Belgians acquired the whole sector. The ore was mainly calamine, then sphalerite and galena. At its peak the activity employed about three hundred workers in the municipality. Transporting the material marked village life: in the first half of the twentieth century boys and women, known as «taissine», also worked by hand; after the war the mule-drawn wagons gave way to cableways, then came mechanical shovels, pneumatic hammers and ventilation systems.
Under the Fascist regime the mines were expropriated and entrusted to S.A. Nichelio e Metalli, a state-owned company, which in 1954 became Sapez and then in succession Ammi, Sanim and Egam. In the 1970s, after the body was broken up, management passed to Eni until the final closure in 1982: investment had become uneconomic compared with those who mined and exported zinc at far lower prices. With the mines the village's economic engine stopped, and holiday tourism took the place of industry alongside farming.
Memory organised itself almost at once. In 1970 a first collection of minerals was born in a private room, which in 1994 became the public museum in the former primary school. The mining question, however, did not close: in 2014 the Australian company Energia Minerals Limited obtained permits to restart activity in the territories of Oltre il Colle, Gorno, Oneta, Premolo and Ardesio; in December 2021 it asked to move the processing of the ore to the former Serbaplast sheds in Zorzone itself, and in February 2022 the municipality sent a negative opinion to the ministry. In June 2022 came the ministry's negative environmental compatibility ruling on the reopening; in 2026 the Ministry of the Environment approved, with conditions, the retrospective assessment of the exploration drilling, which the company intends to resume.
