Langbank is a village on the south bank of the River Clyde in Renfrewshire, Scotland. The name is thought to come from ‘long bank’ (the first part being 'lang' in Scots). It is 9.3 miles/15 km northwest from Paisley (Renfrewshire) and 3.4 miles/5.5 km east from Port Glasgow (Inverclyde) on the A8.HistoryLangbank evolved as a dormitory settlement for Glasgow after the opening of the Glasgow and Greenock Railway in 1841, a function it still performs. Prior to that it was a scattered collection of farms. An 1800 map makes reference to Longbank. It remains on the busy A8 trunk road, a few hundred yards from the start of the M8 motorway. Langbank railway station is on the Inverclyde Line.There are two crannogs on the shoreline of the village; Langbank East crannog is at Westferry, by the start of the M8 motorway, Langbank West crannog is immediately beside the A8 dual carriageway opposite Langbank Parish Church. Both crannogs are only visible at lower states of the tide.Visible along the shoreline west of Langbank and stretching all the way to Port Glasgow are the remains of the timber ponds where the shipyards of the lower Clyde stored timber for use in shipbuilding during the 18th Century.
