• Borgaccio Wall, near the river Toce, which demarcates Pieve Vergonte from the nearby village of Vogogna. It is the remains of a wall of the castle of Pietra Santa, which was destroyed on February 9, 1348, and it is commonly called the Borgaccio.

The industrial chemical plant of Pieve Vergonte was founded in 1915 on the initiative of the Italian Society of Explosive Products (PETS), based in Milan, with 2,500,000 lire of capital. The first product for the military was iodine monochloride of chlorobenzene and phosgene, used during the First World War and later in the African campaign.^{[clarification needed]}

During World War II, the chloralkali process, sulfuric acid, and fertilizers were produced. After the war, shutting down the production of sulphuric acid, Rumianca SpA [it], and then the SIR Group, developed new product lines for the production of DDT and chloroaromatics. These products were used by the United States of America during the Vietnam War.

In 1981, the facilities of this company were transferred to the ENI Group and the ANIC Company. The ANIC, then EniChem, DDT plants ran until June 1996, and remained in production until their sale on July 1, 1997, to Tessenderlo, Italy. The chloralkali, chlorine, and aromatic synthetic HCL are in production for the Tessenderlo Group.

In May 2013, Tessenderlo Group sold Tessenderlo Partecipazioni SpA, and its subsidiary Tessenderlo Italy Srl, to International Chemical Investors Group (ICIG).^[7] The transaction includes the plant in Pieve Vergonte (VB), where there is now an active electrolysis plant, one for chloro-aromatics, and two hydroelectric plants that provide energy.^[8]

The village of Pieve Vergonte produces electricity from hydroelectric power. The largest producer is the Edison Company, with plants in Val Anzasca and Pieve Vergonte, both fed by the waters of the river Anza, with a total average production of 95 GWh. The second-largest producer is Tessenderlo's Battiggio plant, ex-Rumianca of Ceppo Morelli in Val Anzasca, on the Toce river at Megolo, which has a total average production of 90 GWh.^{[citation needed]}

Gold-bearing pyrites were mined in the Toppa Valley using mercury.^[9]
