care. They are now administered by Historic Scotland. Modern history The Jacobite rising known as the Forty-Five turned Arbroath into a Jacobite town. A high proportion of its able-bodied men joined the Jacobite army. It was one of the main ports where men and supplies could be landed from France. It and other Jacobite ports along the north-east coast collectively formed 'an asset of almost incalculable value' to the Jacobite cause. The Industrial Revolution led to an expansion of Arbroath's economy and population. New housing was built for the influx of workers and Arbroath became known for jute and sailcloth production. In 1867, the mills employed 4,620 people and in 1875, 1,400 looms in 34 mills produced over a million yards of osnaburg cloth and 450,000 yards of sailcloth; the town is believed to have supplied the sails for Cutty Sark. Arbroath was also prominent in the making of shoes and lawnmowers. Manufacturer Alexander Shanks, founded in 1840 and based at Dens Iron Works from 1853, supplied mowers to the Old Course at St Andrews and the All England Lawn Tennis and Croquet Club. Shanks was taken over in the 1960s by local firm, Giddings & Lewis-Fraser Ltd., which had evolved from the flax and canvas manufacturing business established by Douglas Fraser in 1832. In the last decade of the 19th century, Douglas Fraser & Sons shifted focus to machine manufacture following the success of a braiding machine designed by Norman Fraser. The firm had interests in South America and India. In 1959 the business was taken over by the US company, Giddings & Lewis and renamed Giddings & Lewis-Fraser. Its headquarters were Wellgate Works, Arbroath. Arbroath is well known for its ties to the fishing industry. Following significant improvements to the harbour in 1839, the council sought fishermen willing to migrate to the town. Men came from nearby Auchmithie and further afield, including Shetland. The industry grew, and in the peak years up to 1980 some 40 whitefish and pelagic vessels worked from Arbroath, employing hundreds on board and hundreds more ashore to service vessels and process the fish. Quota cuts and decommissioning took their toll in Scotland from the 1980s, however Arbroath remains a whitefish port open for landing shellfish. Only one vessel now works regularly from Arbroath; though a further three Arbroath-owned vessels work from Aberdeen and ports further north. Fish processing remains a big employer, but
