River Ribble in the context of River Dee, Cumbria

Preston (/ˈprɛstən/ ) is a city on the north bank of the River Ribble in Lancashire, in North West England. The city is the administrative centre of the county of Lancashire and the wider City of Preston local government district. Preston and its surrounding district obtained city status in 2002, becoming England's 50th city in the 50th year of Queen Elizabeth II's reign. Preston had a population of 147,835 at the 2021 census, the City of Preston district 156,411 in 2023 and the Preston Built-up Area 313,322. The Preston Travel To Work Area, in 2011, had a population of 420,661, compared with 354,000 at the previous census. The south bank of the Ribble is part of the Preston urban area, although it forms the South Ribble borough that is administratively separate.

Preston and its surrounding area have provided evidence of ancient Roman activity, largely in the form of a Roman road that led to a camp at Walton-le-Dale. The Angles established Preston; its name is derived from the Old English meaning "priest's settlement" and in the Domesday Book is recorded as "Prestune". In the Middle Ages, Preston was a parish and township in the hundred of Amounderness and was granted a Guild Merchant charter in 1179, giving it the status of a market town. Textiles have been produced since the mid-13th century when locally produced wool was woven in people's houses. Flemish weavers who settled in the area in the 14th century helped develop the industry. In the early-18th century, Edmund Calamy described Preston as "a pretty town with an abundance of gentry in it, commonly called Proud Preston". Sir Richard Arkwright, inventor of the spinning frame, was born in the town. The most rapid period of growth and development coincided with the industrialisation and expansion of textile manufacturing. Preston was a boomtown of the Industrial Revolution, becoming a densely populated engineering centre, with large industrial plants. The town's textile sector fell into terminal decline from the mid-20th century and Preston has subsequently faced similar challenges to other post-industrial northern towns, including deindustrialisation, economic deprivation and housing issues.

Blackburn (/ˈblækbɜːrn/ ) is an industrial town and the administrative centre of the Blackburn with Darwen borough in Lancashire, England. The town is north of the West Pennine Moors on the southern edge of the Ribble Valley, 8 mi (13 km) east of Preston and 21 mi (34 km) north-northwest of Manchester. Blackburn is at the centre of the wider unitary authority area along with the town of Darwen. It is the second largest town (after Blackpool) in Lancashire.

At the 2011 census, Blackburn had a population of 117,963, whilst the wider borough of Blackburn with Darwen had a population of 150,030; 30.8% of the population of town were people of ethnic backgrounds other than white British.

The Forest of Bowland, also known as the Bowland Fells and formerly the Chase of Bowland, is an area of gritstone fells, deep valleys and peat moorland, mostly in north-east Lancashire, England, with a small part in North Yorkshire (however roughly half of the area falls into the area of the historic West Riding of Yorkshire). It is a western outlier of the Pennines.

The Forest of Bowland was designated an Area of Outstanding Natural Beauty (AONB) in 1964. The AONB also includes a detached part known as the Forest of Pendle separated from the main part by the Ribble Valley, and anciently a royal forest with its own separate history. One of the best-known features of the area is Pendle Hill, which lies in Pendle Forest. There are more than 500 listed buildings and 18 scheduled monuments within the AONB.

The City of Preston, or simply Preston (/ˈprɛstən/ ), is a local government district with city status in Lancashire, England. It lies on the north bank of the River Ribble and has a population of 162,864 (2024). The neighbouring districts are Ribble Valley, South Ribble, Fylde and Wyre.

The district is named after its largest settlement, Preston, which lies in the south of the district. The district also includes rural areas to the north of the main urban area, including part of the Forest of Bowland, a designated Area of Outstanding Natural Beauty. In 2002 the district was granted city status to mark the Golden Jubilee of Elizabeth II; prior to this it was known as the Borough of Preston, having held borough status since its creation in 1974.

Walton-le-Dale is a large village in the borough of South Ribble, in Lancashire, England. It lies on the south bank of the River Ribble, opposite the city of Preston, adjacent to Bamber Bridge. The population of the South Ribble Ward at the 2011 census was 3,792. To the west of Walton-le-Dale is the residential area of Walton Park.

The Amounderness Hundred (/əˈmʌndərnəs/ ə-MUN-dər-nəs) is one of the six subdivisions of the historic county of Lancashire in North West England, but the name is older than the system of hundreds first recorded in the 13th century and might best be described as the name of a Norse wapentake. In the Domesday Book of 1086, it was used for some territories north of the River Ribble included together with parts of Yorkshire. The area eventually became part of Lancashire, sitting geographically between the Rivers Lune and Ribble, in the strip of coast between the Irish Sea and Bowland Forest.

The Pennines (/ˈpɛnaɪnz/), also known as the Pennine Chain or Pennine Hills, are an upland range mainly located in Northern England. Sometimes described as the "backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the north of the Midlands to Northumberland in North East England. From the Tyne Gap in the north, the range extends south through the North Pennines, Yorkshire Dales, South Pennines, and Peak District to end near the valley of the River Trent. The Border Moors and Cheviot Hills, which lie beyond the Tyne Gap, are included in some definitions of the range.

The range is divided into two by the Aire Gap, a wide pass formed by the valleys of the rivers Aire and Ribble. There are several spurs off the main Pennine range east into Greater Manchester and Lancashire, comprising the Rossendale Fells, West Pennine Moors, and Bowland Fells. The Howgill Fells and Orton Fells in Cumbria are also sometimes considered to be Pennine spurs. The Pennines are an important water catchment area, with numerous reservoirs in the head streams of the river valleys.

The Ribblehead Viaduct or Batty Moss Viaduct carries the Settle–Carlisle railway across Batty Moss in the Ribble Valley at Ribblehead, in North Yorkshire, England. The viaduct, built by the Midland Railway, is 28 miles (45 km) north-west of Skipton and 26 miles (42 km) south-east of Kendal. It is a Grade II* listed structure. Ribblehead Viaduct is the longest and the third tallest structure on the Settle–Carlisle line.

The viaduct was designed by John Sydney Crossley, chief engineer of the Midland Railway, who was responsible for the design and construction of all major structures along the line. The viaduct was necessitated by the challenging terrain of the route. Construction began in late 1869. It necessitated a large workforce, up to 2,300 men, most of whom lived in shanty towns set up near its base. Over 100 men lost their lives during its construction. The Settle to Carlisle line was the last main railway in Britain to be constructed primarily with manual labour.

The Yorkshire Dales are a series of valleys, or dales, in the Pennines, an upland range in England. They are mostly located in the ceremonial county of North Yorkshire, but extend into Cumbria and Lancashire; they are entirely within the historic boundaries of Yorkshire. The majority of the dales are within the Yorkshire Dales National Park, created in 1954. The exception is the area around Nidderdale, which forms the separate Nidderdale Area of Outstanding Natural Beauty.

The landscape of the Yorkshire Dales consists of sheltered glacial valleys separated by exposed moorland. The predominant rock is Carboniferous Limestone, which is particularly visible in the south-west in features such as Malham Cove. It is overlain in many areas by the Yoredale Series of alternating weak shales and hard limestones and sandstones, which give the dales their characteristic 'stepped' appearance. Most of the dales contain rivers, and the area contains seven primary catchments: the Swale, Ure, Wharfe, Aire, Nidd, Ribble, and Lune. There are several notable cave systems in the area, including part of the longest system in the United Kingdom, the Three Counties.
