Troon is now most famous for its associations with golf and the town hosted the British Open Tournament in 1997. However, Troon owes its origins to coal and the railways. In 1812, the Duke of Portland, who had acquired much of the coal-bearing land around Kilmarnock, opened a railway from the mines to Troon, where he had earlier commissioned the creation of a harbour. Troon Harbour was built from a rocky headland which provides shelter from westerly on-shore storms. Troon was one of several Ayrshire ports developed for the export of coal, mainly to Ireland. By the 1830s, 50,000 tons were being exported annually through Ayr's ports. A hundred years later, over 3,000,000 tons were being handled by all Ayrshire ports. The 1940s began a decline in coal production, which was briefly interrupted in the early 1970s, before ceasing altogether.
Troon Harbour has always been home of a few fishing boats and other vessels, but has become a popular leisure cruising centre with it's own marina. The Ayrshire Fish Market moved from Ayr to Troon in 1996.
The town of Troon was laid out in a conventional grid pattern, curved to fit the headland. This replacing the few fisherman's huts which had previously existed as Troon village. Housing also developed along the South Beach Road, where better villas were built. The hinterland of the town has some substantial houses, built for the Fullarton family, for the Duke of Portland and other business men.
Charles Kerr Marr was a native of Troon. He died in 1919 his wife having died childless in 1892. They are interred in Cathcart Cemetery, Glasgow. Mr Marr's considerable fortune which was made in the coal industry, was left for the benefit of the townspeople of Troon as the C.K. Marr Educational Trust.
To the north of the town lies Barassie (sometimes known as New Kilmarnock), originally a small settlement of weekend houses built on the coast for Kilmarnock merchants. The 1911 scheme to develop it as Garden Village was curtailed by the First World War. Development restarted in the inter-war years with the addition of many bungalows. from the 1970s, Barassie has developed into a substantial suburb.
