Blackpool ) is a borough, seaside town, and unitary authority area of Lancashire, in North West England. It is situated along England's west coast by the Irish Sea, between the Ribble and Wyre estuaries, 17.5 mi northwest of Preston, 30 mi north of Liverpool, and 40 mi northwest of Manchester. It has a population of 142,900, making it the third most populous settlement in North West England, and a population density which makes it the fourth most densely populated district of England and Wales outside Greater London.Throughout the Middle Ages and Early Modern period, Blackpool was a coastal hamlet in Lancashire's Hundred of Amounderness, and remained such until the mid-18th century when it became fashionable in England to travel to the coast during Summer to bathe in sea water to improve wellbeing. In 1781, visitors attracted to Blackpool's 7 mi sandy beach were able to use a newly-built private road, built by Thomas Clifton and Sir Henry Hoghton. Stagecoaches began running to Blackpool from Manchester in the same year, and from Halifax in 1782. In the early-19th century, Henry Banks and his son-in-law John Cocker erected new buildings in Blackpool such that its population grew from less than 500 in 1801 to over 2,500 in 1851. St John's Church in Blackpool was consecrated in 1821.Blackpool rose to prominence as a major centre of tourism in England when a railway was built in the 1840s connecting it to the industrialised regions of northern England. The railway made it much easier and cheaper for visitors to reach Blackpool, triggering an influx of settlers, such that in 1876 Blackpool was incorporated as a borough, governed by its own town council and aldermen. In 1881 Blackpool was a booming resort with a population of 14,000 and a promenade complete with piers, fortune-tellers, public houses, tram and donkey rides, fish-and-chip shops, theatres. By 1901 the population of Blackpool was 47,000, by which time its place was cemented as "the archetypal British seaside resort". By 1951 it had grown to 147,000.Shifts in tastes and sensibilities, combined with opportunities for Britons to travel overseas, supplanted Blackpool's status as a leading resort during the late-20th century. Nevertheless, Blackpool's urban fabric and economy remains relatively undiversified, and firmly rooted in the tourism sector, and the borough's seafront continues to attract millions of visitors every year. In addition to its sandy beaches, Blackpool's major attractions and landmarks include the Blackpool Tower, Blackpool Illuminations, the Pleasure Beach Blackpool, and the Winter Gardens. Blackpool is also noted for its political autonomy, independent of Lancashire County Council.
