Poulton became an important centre for trade in the area. With harbours on either side of the River Wyre, at Skippool and Wardleys, it was able to import goods from as far away as Russia and North America. Flax was imported from Ireland and the Baltic, timber came from across the Atlantic and tallow from Russia. Records from 1806 to 1808 show that Poulton imported limestone from Ulverston, oats from Ulverston, Kirkcudbright, Dumfries, Wigtown, Whitehaven and Liverpool, and coal from Preston. Cheese was exported to the same places. By the 18th century, markets for cattle and cloth were being held in the town in February, April and November, with corn fairs every Monday. It is unclear at what point Poulton began life as a market town; it was never granted a market charter and so markets were held by prescription. The market cross probably dates from the 17th century.
