Blackpool is a seaside resort town in Lancashire, England. It is located on the Irish Sea coast of the Fylde peninsula, approximately 27 miles (43 km) north of Liverpool and 14 miles (23 km) west of Preston. It is the main settlement in the borough of the same name. The population of Blackpool at the 2021 census was 141,000, a decrease of 1,100 in ten years.
Blackpool was originally a small hamlet; it began to grow in the mid-eighteenth century, when sea bathing for health purposes became fashionable. Blackpool's beach was suitable for this activity, and by 1781 several hotels had been built. The opening of a railway station in the 1846 allowed more visitors to reach the resort, which continued to grow for the remainder of the nineteenth century. In 1876, the town became a borough, and by 1951 its population had reached 147,000. Blackpool's development was closely tied to the Lancashire cotton-mill practice of annual factory maintenance shutdowns, known as wakes weeks, when many workers chose to visit the seaside.
