The Pistoiese Mountains (Italian: Montagna pistoiese or Appennino pistoiese) are a historical and geographical mountain region in the Province of Pistoia, Tuscany, central Italy. They occupy the southern side of the Tuscan-Emilian Apennines, north and north-west of the city of Pistoia, and include the upper valleys of the Reno, Lima, Sestaione, Maresca, Orsigna, Limentra and Ombrone Pistoiese.
The region is not a single administrative unit. Its present administrative core is formed by the mountain municipalities of Abetone Cutigliano, San Marcello Piteglio and Sambuca Pistoiese, which belong to the Unione di Comuni Montani Appennino Pistoiese. In a broader historical and cultural sense, the Pistoiese Mountains are also commonly associated with Marliana and with the mountain areas of the municipality of Pistoia.
Regione Toscana identifies the Montagna pistoiese as an Apennine landscape area extending from the Alpe Tre Potenze to Monte La Croce, near the Forest of Acquerino. Its landscape combines high ridges, extensive forests, dispersed villages, chestnut and pastoral areas, historic trans-Apennine routes, railway infrastructure, former industrial settlements and sites connected with mountain crafts and wartime memory.
Historically, the region was shaped by forestry, chestnut cultivation, pastoralism, iron-working, natural ice production, road and railway links across the Apennines, and twentieth-century industrial development. Its main cultural and landscape features include the Porrettana railway, the former Ferrovia Alto Pistoiese, the Ecomuseo della Montagna Pistoiese, the forests of Teso and Acquerino, the high-mountain area of Abetone and Val di Luce, the industrial village of Campo Tizzoro, and historic settlements such as Cutigliano, Gavinana, Popiglio, Maresca, Orsigna, Pavana, Treppio and Sambuca Castello.
The natural value of the Pistoiese Mountains is also reflected in a network of protected areas and Natura 2000 sites, including Alta Valle del Sestaione, Campolino, Abetone, Pian degli Ontani, Libro Aperto - Cima Tauffi, Monte Spigolino - Monte Gennaio and Tre Limentre - Reno. One of the most significant sites is the Campolino State Nature Reserve, which protects native Norway spruce stands regarded as possible glacial relicts and peatland habitats of scientific importance.
Name and extent
The Italian expression Montagna pistoiese literally refers to the mountain area associated with Pistoia, while Appennino pistoiese emphasises its position within the Apennine chain. English-language institutional and tourist sources use forms such as "Pistoiese Mountains", "Pistoia Mountains" and "Pistoian Mountain Region".
The name was already in use in nineteenth-century descriptions of the area, including Giuseppe Tigri's Guida della montagna pistoiese, published in its third edition in 1878 under the auspices of the Florentine section of the Club Alpino Italiano.
The limits of the region are historical and geographical rather than strictly administrative. Regione Toscana's landscape documentation defines the Montagna pistoiese as extending from the Alpe Tre Potenze to Monte La Croce, near the Forest of Acquerino, and as bounded by the provinces of Modena and Bologna to the north and north-west, by the province of Lucca to the west, and by the Reno and the municipal boundaries of Marliana and Pistoia to the south and south-west.
In administrative terms, much of the area is represented by the Unione di Comuni Montani Appennino Pistoiese, comprising Abetone Cutigliano, San Marcello Piteglio and Sambuca Pistoiese. Regione Toscana records a total surface area of 287.42 square kilometres and a population of 11,019 as of 31 December 2021 for these three municipalities. The wider cultural area is also commonly associated with Marliana and with the mountain portion of the municipality of Pistoia.
Geography
The Pistoiese Mountains lie on the southern flank of the Tuscan-Emilian Apennines. Their western and northern sectors are the highest, around the Abetone Pass, the Val di Luce, the upper Sestaione valley, the Doganaccia and the ridge system towards the Alpe Tre Potenze. The eastern and south-eastern sectors are lower, more wooded and more deeply incised by streams; the Teso, Orsigna, Limentra and Acquerino areas form some of the region's most extensive forest landscapes.
The high-mountain sector includes some of the best-known natural sites of the area. The Lago Nero, situated below the Alpe Tre Potenze at the head of the Sestaione valley, is one of the emblematic high-altitude lakes of the Pistoiese Mountains; nearby routes connect it with Lago Piatto, the Alpe Tre Potenze and the Val di Luce. The Doganaccia, above Cutigliano, gives access to watershed routes towards the Croce Arcana and Lago Scaffaiolo.
Forests are a defining feature of the region. The Foresta del Teso extends for more than 2,000 hectares, from about 795 to 1,732 metres above sea level, between Pracchia and San Marcello Pistoiese, with its core around Maresca and Orsigna. On the eastern side of the region, the Forest of Acquerino is a biogenetic nature reserve and includes an archaeological park connected with the Stone Itinerary of the Ecomuseo della Montagna Pistoiese.
Regione Toscana's landscape documentation records an extensive public forest estate in the area, including the forests of Abetone-Boscolungo, Melo, Lizzano-Spignana and Maresca, with a total surface of about 101 square kilometres. The Foresta del Teso is associated with a varied Apennine fauna, including red deer, fallow deer, roe deer, wild boar, mouflon, buzzards, badgers, porcupines, foxes, wolves and several mustelids, as well as bird species such as woodpeckers, dunnocks and song thrushes. The Acquerino area is characterised by almost continuous woodland cover, conifer plantations and ecologically valuable open meadows; the tree flora includes species such as sycamore maple, wild cherry, rowan, ash and goat willow.
The historical landscape was strongly influenced by chestnut cultivation. In the nineteenth century, Giuseppe Tigri described the chestnut woods of the Montagna pistoiese as a distinctive element of the mountain economy and environment. For centuries, woodland resources supported charcoal production, timber extraction, pastoralism, chestnut cultivation, iron working and seasonal labour, making the forest both a natural environment and an economic infrastructure of mountain life.
Nature conservation
The Pistoiese Mountains include several protected areas, state nature reserves and Natura 2000 sites. The high western sector around Abetone and the upper Sestaione valley includes the sites Alta Valle del Sestaione, Campolino, Abetone, Pian degli Ontani, Libro Aperto - Cima Tauffi and Monte Spigolino - Monte Gennaio, while the eastern forested sector includes the larger Tre Limentre - Reno site.
A particularly important conservation area is the Campolino State Nature Reserve, near Abetone Cutigliano. The reserve is classified as an oriented and biogenetic reserve and overlaps with the Campolino Special Protection Area and the Alta Valle del Sestaione Special Area of Conservation. It protects one of the southernmost native Norway spruce (Picea abies) populations in Italy, considered a possible glacial relict, together with peatlands, wetlands, rocky habitats and small lakes such as Lago del Greppo and Lago delle Bruciate.
The reserve's habitats include alpine and boreal heaths, species-rich Nardus grasslands, hydrophilous tall-herb fringes, transition mires, siliceous screes and rocky slopes, beech forests and acidophilous montane and alpine Picea forests. Its vegetation reflects the ecological transition between beech, silver fir, Norway spruce, montane heath and high-altitude grassland communities.
Settlement pattern and administration
The Pistoiese Mountains are characterised by small towns, villages, hamlets and scattered houses rather than by a single dominant centre. San Marcello Piteglio forms the central sector of the region, with settlements such as San Marcello Pistoiese, Maresca, Gavinana, Campo Tizzoro, Popiglio and Piteglio. Abetone Cutigliano includes the highest-altitude part of the mountain area, including Abetone, Cutigliano, Pian degli Ontani, Pian di Novello, Doganaccia and Val di Luce. Sambuca Pistoiese occupies the north-eastern borderland towards Bologna, with villages such as Pavana, Treppio, Torri, Taviano and Sambuca Castello. Marliana forms the south-eastern edge of the historical mountain region, facing the Valdinievole. Within the municipality of Pistoia, localities such as Pracchia and Le Piastre are linked respectively with the Porrettana railway and with the historic ice-production economy of the upper Reno valley.
Historically, the role of the main centre changed over time. Regione Toscana notes that Cutigliano was once the seat of the Capitano della Montagna, while San Marcello Pistoiese later became the most important centre of the area. Treccani also describes San Marcello Pistoiese as the former capital and present main centre of the Montagna pistoiese.
The dispersed character of settlement is especially marked in Sambuca Pistoiese. Municipal planning documents describe a population distributed among centres, nuclei and scattered houses, with a strong imbalance between denser villages such as Pavana and sparsely populated mountain areas such as Torri and Monachino.
Railways and transport landscape
Railways are central to the modern identity of the Pistoiese Mountains. The area is crossed by the Porrettana railway and was formerly served by the narrow-gauge Ferrovia Alto Pistoiese. Together they connected Pistoia, the upper Reno valley, the industrial settlements of the central mountains and the borderland towards Bologna.
Porrettana railway
The Porrettana railway is one of the most important historic infrastructures of the region. It was the first railway line to connect Pistoia and Bologna across the Tuscan-Emilian Apennines. Designed by the French engineer Jean Louis Protche, it includes 47 tunnels and 35 bridges and viaducts, and was officially inaugurated by King Victor Emmanuel II on 2 November 1864.
Before the opening of the Direttissima in the twentieth century, the Porrettana represented the main railway route from central Italy towards the north through the Apennines. On the Pistoiese side, the railway landscape is closely associated with the stations and villages of Piteccio, Corbezzi, Castagno, San Mommè and Pracchia. Visit Tuscany describes the mountain section as beginning from Pistoia railway station and continuing through these stations before reaching the Emilian side of the Apennines.
Pracchia was an important railway locality on the upper Reno. Treccani describes it as a village of the Montagna pistoiese on the upper course of the Reno, served by the Porrettana railway and formerly connected with San Marcello Pistoiese and Mammiano by a narrow-gauge railway.
The Pistoiese section has also generated footpaths and local projects, including the Sentiero delle Stazioni, an itinerary linking the stations of the Porrettana on the Pistoiese side of the Apennines.
Ferrovia Alto Pistoiese
The former Ferrovia Alto Pistoiese (FAP), also known as the Pracchia-San Marcello Pistoiese-Mammiano railway, was a 950 mm narrow-gauge, electrically powered line serving the central mountain area. It linked Pracchia with Mammiano through Pontepetri, Campo Tizzoro, Maresca, Oppio, Gavinana, Limestre and San Marcello Pistoiese. SIUSA records the company as established in 1916 for the construction and operation of the Pracchia-Mammiano line, which was inaugurated in 1926 and connected the inhabited centres and factories of the area.
