Wigan was described by Celia Fiennes, a traveller, in 1698 as "a pretty market town built of stone and brick". In 1720, the moot hall was rebuilt, funded by the members of the borough. It was used as the town hall and the earliest reference to it dates from the 15th century. Prior to its final destruction in 1869, the hall was rebuilt in 1829. Wigan's status as a centre for coal production, engineering and textiles in the 18th century led to the Douglas Navigation in the 1740s, the canalisation of part of the River Douglas and later the Leeds and Liverpool Canal. The canal from Liverpool to Leeds was originally to serve Wigan on a spur, transporting cloth and food grown on the West Lancashire Plain to the Port of Liverpool. When construction restarted in the 1790s, after decades pause, as coal was rising in importance due to the progress of the Industrial Revolution. The route was altered at the request of mill owners, with the spur becoming the primary route and Wigan a hub for transport of coal from the Lancashire coal pits to Liverpool and Leeds.
