An early wooden bridge over the Looe River was in place by 1411, which burned down and was replaced by the first stone bridge, completed in 1436 and featured a chapel dedicated to St Anne in the middle (the current bridge, a seven-arched Victorian bridge, was opened in 1853). By this time Looe had become a major port, one of Cornwall's largest, exporting local tin, arsenic and granite, as well as hosting thriving fishing and boatbuilding industries. The town was able to provide some 20 ships for the Siege of Calais in 1347.
