In 1833 a canal and a railway reached the area; the Sankey Canal was extended to a point on the River Mersey to the east of Runcorn Gap and the St Helens and Runcorn Gap Railway established a terminus adjacent to the canal.
Widnes Dock, the world's first railway dock, was established at the new terminal, The town's listed buildings reflect its history.
The oldest, St Luke's Church in the former village of Farnworth, dates from the 12th century.
Also built before 1847 are three houses, a bridewell adjacent to St Luke's Church, and the lock at the terminus of the Sankey Canal.The buildings from after 1847—three churches and the cemetery chapels, one public building (the town hall), two railway stations, two bridges crossing the River Mersey, and the former power house of the now-demolished transporter bridge—largely reflect the growing population of the town and its increasing transport links.The Tower Building, formerly an office and now a museum, and a sewer vent, relate to the chemical industry.The latest structure to be listed is a war memorial in Victoria Park.Other than the bridges and the lock, the building materials used are brick or local red sandstone.St Luke's is a parish church constructed in red sandstone dating from the late 12th century. There were later additions and restorations, the final restoration being in 1894–95.
