Cromarty Firth: Through The Ages

Once a single landmass, the twin headlands of North and South Sutor guard the entrance to the Firth. Glaciers forge a channel through the 700 million year old rocks, creating a deep natural harbour and carrying the detritus that will form the mudflats of the Firth.

Marine life, then birds and mammals, flock to these nutrient rich habitats. Nomadic hunter-gatherers are attracted by migrating birds – and they in turn are followed by Neolithic farmers. By early Bronze Age times, the first sea-crossings are beginning to evolve into trade links.

From the 2nd century BC, a more formalised tribal society begins to emerge under the influence of the Iron Age Celts with small stone forts appearing at numerous locations such as Castledownie, North Sutor, Culbokie and Scotsburn.

By the 3rd century AD, the mysterious Picts dominate most of the eastern part of Scotland. In Easter Ross, their sophisticated religious and social system produces a legacy of elaborate stone carvings.

From the 6th century onwards, the Picts are converted to Christianity and Christian symbols feature in their stone carvings such as the famous Cadboll stone. A battle for political control over the eastern seaboard centres on the Cromarty Firth, with Vikings and Scots vying with the Picts for ascendancy. In the aftermath of conflict the powerful Christian Church pacifies an unsettled region.

In 1263, the remains of St Duthac are returned to his birthplace in Tain. His shrine becomes a place of pilgrimage, visited on several occasions by King James IV. The pilgrims’ route follows an ancient network of paths and ferry crossings, including the Cromarty-Nigg ferry which was also used in the 1300s by Robert the Bruce.

In the Middle Ages, feudal landlords and family dynasties owing allegiance to the Scottish Crown shape the fortunes of the Firth. The clans Munro, MacKenzie, Ross and Urquhart assert their dominance building castles and developing trade links.

By the 18th century, Cromarty is flourishing, profiting from the export of grain, salmon, herring and cod. George Ross purchases the Cromarty Estate in 1767 and builds hemp and linen factories. John Smeaton builds Cromarty harbour in 1784. Hugh Miller is born at the height of Cromarty’s prosperity in 1802 and goes on to write seminal works on geology, Highland culture and theology.

In 1914, Winston Churchill visits South Sutor to authorise the building of forts and gun emplacements. An enormous metal net is stretched between South and North Sutors to stop submarines from entering. The Firth becomes a strategic naval base centred on the port of Invergordon and the local population surges. In 1915, a huge explosion mysteriously destroys HMS Natal with the loss of 400 lives. (The victims of this tragic event are remembered in a commemorative garden created in Invergordon.)

During the Second World War (1939-45), the Firth not only continues to serve as an important naval base, but the Royal Air Force also establishes an air field at Alness Point.

In the 1960s, the discovery of North Sea oil and the construction of an aluminium smelter at Invergordon marks a new chapter in the history of the Firth. The Nigg oil fabrication yard opens in 1974, at the time the largest dry dock in the world.

2001. A new millennium, and the prosperity of the Firth remains linked to the sea. It is the main UK location for maintaining oilrigs and other offshore units. Oil is piped direct to the Nigg Oil Terminal from the Beatrice field in the Moray Firth. International shipping and cruise liners make regular use of Invergordon’s deep-water harbour. High technology business parks stand close to ancient grain stores.
