Closed coal shaft site at Germunde, the last underground workings of the Couto Mineiro do Pejão, closed in 1994, with surviving surface structures on private land.
Poço Germunde 2, also referred to as PG-II, is a coal shaft site within the Germunde mining area, forming part of the Couto Mineiro do Pejão in the Douro Coalfield of northern Portugal. The Germunde sector, located in the parish of Pedorido, Castelo de Paiva, was the final zone of active underground coal extraction in the entire Douro Carboniferous Basin before the complex closed on 31 December 1994. The mine was operated by the Empresa Carbonífera do Douro (ECD), founded in 1917 and later transferred to Ferrominas in 1984.
The Germunde anthracite mine had three vertical shafts and nine exploration levels reaching a maximum depth of 480 metres. Poço Germunde 2 is the second of these shafts. Post-closure, the site entered private ownership.
Surface structures including the shaft tower survived in deteriorating condition. As of 2022, municipal heritage plans included recovery of Poço Germunde 1 and the associated Casa da Malta; the status of Poço Germunde 2 structures remained unresolved.
The Couto Mineiro do Pejão, the coal mining concession that encompassed the Germunde area, has its origins in 1859 when the Conselho d'Obras Públicas e Minas examined evidence of coal deposits at Monte das Cavadinhas in Pejão, in the parish of São Pedro do Paraíso, Castelo de Paiva. The earliest known concessions date from 1884, when an English company began the first prospecting and extraction work. Between 1908 and 1917 the concession was held jointly by the Companhia Portuguesa de Carvão and Anglo-Portuguesa Colliers, Lda. In 1917, the Empresa Carbonífera do Douro, Lda. (ECD) was founded with a capital of 200 contos, consolidating the concession under a single operator. The First World War (1914–1918) provided the initial strong impetus to production.
Coal outcrops had been identified not only at Pejão but at a series of additional locations extending across the concession: Folgoso, São Domingos, Arda, Serrinha, Paraduça, and Germunde. Together with the original Pejão workings, these formed the Couto Mineiro do Pejão, extending approximately ten kilometres from the place of Germunde at the western end to the Alto do Pejão at the eastern. Germunde, situated in Pedorido on the left bank of the Douro, became the principal centre of extraction and the location of the main surface installations of the ECD.
In 1933, following the bankruptcy of the ECD, the company was acquired by a Belgian consortium led by Jean Tyssen. Under Belgian administration the enterprise underwent substantial development in production capacity, infrastructure, and social provision. The company reached peak production in 1957. The Germunde anthracite mine developed three vertical shafts and nine exploration levels, reaching a maximum depth of 480 metres. The mining method employed was a variant of sublevel caving. A narrow-gauge railway in the Decauville system, with a gauge of 600 millimetres, was constructed to carry coal from the Pejão sector to a river quay at Germunde on the Douro for onward transport; this ferroviária and fluvial transport system remained in use until 1974.
In May 1963 the ECD was restructured as a sociedade anónima de responsabilidade limitada under the designation Empresa Carbonífera do Douro, S.A.R.L. In 1977 the company was acquired by the Portuguese state, though it continued to operate under its existing company statute. In 1984, under an arrangement between the Instituto de Participações do Estado, E.P. and Ferrominas, the ECD passed to the latter entity.
Poço Germunde 2 (PG-II) was one of the three vertical shafts of the Germunde mine. The Germunde sector represented the last zone of active underground exploitation in the entire Douro Carboniferous Basin. Following decades of decline in the competitiveness of European coal relative to hydrocarbons and lower-cost producing countries, the Minas do Pejão were closed officially on 31 December 1994 by government decision, ending more than a century of extraction in the couto. The closure was accompanied by significant worker protests and industrial action.
Post-closure, the surface structures of the Germunde complex, including the Poço Germunde 2 tower, entered private ownership following an exchange of land with the former ECD installations. By 2010 the PG-II tower was described as being in deteriorating condition, with zinc sheeting cladding the structure. No heritage classification has been identified for Poço Germunde 2 in the consulted sources. As of 2022, municipal recovery plans for the Couto Mineiro do Pejão focused on Poço Germunde 1 and the Casa da Malta as priority heritage structures, while broader interpretation of the coalfield was being developed through the Núcleo de Experiências Turísticas do Couto Mineiro do Pejão opened in May 2022 at Pedorido. The geological heritage of the Germunde mining area continues to be recognised for its scientific value within the Douro Carboniferous Basin, and gallery entries remain directly visible at the site.
