The town is well known for the Invergordon Mutiny of 1931. More recently it has also become known for the repair of oil rigs which line up in the Cromarty Firth on which the town is situated. In the 1970s and 1980s nearby Nigg was known for the construction of these rigs. The yard used for this is now attempting to re-establish itself as a fabricator of large offshore wind turbines and oil rig refurbishment since being purchased by Global Energy Group.

For a number of years Invergordon was the site of an aluminium smelter until 1981 when British Aluminium closed it down. The pipeline that covered the conveyor belt from the smelter to the BA pier was not dismantled until the early 2000s and the two large tanks still stand today as well as a water tower.

It still has a grain whisky distillery, operated by Philippines-owned whisky giant Whyte and Mackay, the output of which contributes to many blended whiskies. Connected to the distillery was the Invergordon Distillery Pipe Band.

At present the port is visited by many large cruise liners each year, as the deep water port allows disembarkation for coach tours in the northern Highlands.

Since the 1970s some would perceive the town as a 'Glasgow colony', since many workers were recruited from southern Scotland to work in the oil rig fabrication and aluminium smelting industries. As a result, the residents' accents often show more influence from Glasgow, than the surrounding Easter Ross dialect of Highland Englishalthough this has changed in recent years.

In recent years Global Energy Group have been expanding, with the purchase of the Nigg fabrication yard it has also brought much appreciated work to Invergordon's Docks with the town again full of oil company workers through the day.

Dublin is the capital of, and largest city in, Ireland. It is on the east coast of Ireland, in the province of Leinster, at the mouth of the River Liffey, and is bordered on the south by the Wicklow mountains. It has an urban area population of 1,173,179, while the population of the Dublin Region (formerly County Dublin), as of 2016, was 1,347,359, and the population of the Greater Dublin area was 1,904,806.

There is archaeological debate regarding precisely where Dublin was established by Celtic-speaking people in the 7th century AD. Later expanded as a Viking settlement, the Kingdom of Dublin, the city became Ireland's principal settlement following the Norman invasion. The city expanded rapidly from the 17th century and was briefly the second largest city in the British Empire before the Acts of Union in 1800. Following the partition of Ireland in 1922, Dublin became the capital of the Irish Free State, later renamed Ireland.

Dublin is a historical and contemporary centre for education, the arts, administration and industry. As of 2018 the city was listed by the Globalization and World Cities Research Network (GaWC) as a global city, with a ranking of "Alpha -", which places it amongst the top thirty cities in the world.

Belfast is a port city in the United Kingdom and the capital city of Northern Ireland, on the banks of the River Lagan on the east coast of Ireland. It is the largest city in Northern Ireland and second largest on the island of Ireland. It had a population of 333,871 in 2015.

By the early 1800s Belfast was a major port. It played a key role in the Industrial Revolution, becoming the biggest linen producer in the world, earning it the nickname "Linenopolis". By the time it was granted city status in 1888, it was a major centre of Irish linen production, tobacco-processing and rope-making. Shipbuilding was also a key industry; the Harland and Wolff shipyard, where the RMS Titanic was built, was the world's biggest shipyard. It also has a major aerospace and missiles industry. Industrialisation and the inward migration it brought made Belfast Ireland's biggest city and it became the capital of Northern Ireland following the Partition of Ireland in 1922. Its status as a global industrial centre ended in the decades after the Second World War.

Belfast suffered greatly in the Troubles, and in the 1970s and 1980s was one of the world's most dangerous cities. However, the city is now considered to be one of the safest within the United Kingdom. Throughout the 21st century, the city has seen a sustained period of calm, free from the intense political violence of former years and has benefitted from substantial economic and commercial growth. Belfast remains a centre for industry, as well as the arts, higher education, business, and law, and is the economic engine of Northern Ireland. Belfast is still a major port, with commercial and industrial docks dominating the Belfast Lough shoreline, including the Harland and Wolff shipyard. It is served by two airports: George Best Belfast City Airport, and Belfast International Airport 15 miles (24 km) west of the city. It is listed by the Globalization and World Cities Research Network (GaWC) as a Gamma global city.
