Newcastle upon Tyne, often shortened to Newcastle, is a city and metropolitan borough of Tyne and Wear, in North East England. Situated on the north bank of the River Tyne, the city grew as an important centre for the wool trade and it later became a major coal mining area. The port developed in the 16th century and, along with the shipyards lower down the river, was amongst the world's largest shipbuilding and ship-repairing centres. These industries have since experienced severe decline and closure, and the city today, is largely a business and cultural centre, with a particular reputation for nightlife.

Belfast (meaning: "mouth of the sandbanks") is the capital and largest city of Northern Ireland, the second-largest city in Ireland after Dublin, and is situated around the River Lagan, which runs through the city. It is a port city known as the birthplace of the RMS Titanic, and for its political murals, documenting the ‘Troubles’ of the 20th century. Today, Belfast remains a centre for industry, as well as the arts, higher education, business, and law, and is the economic engine of Northern Ireland. The city suffered greatly during the period of conflict called "the Troubles", but latterly has undergone a sustained period of calm, free from the intense political violence of former years, and substantial economic and commercial growth. Additionally, Belfast city centre has undergone considerable expansion and regeneration in recent years, notably around Victoria Square.

New Haven in the U.S. state of Connecticut, is the principal municipality in Greater New Haven. It is the second-largest city in Connecticut. It was founded in 1638 by English Puritans, and a year later eight streets were laid out in a four-by-four grid, creating what is now commonly known as the "Nine Square Plan", now recognized by the American Institute of Certified Planners as a National Planning Landmark. The central common block is New Haven Green, a 16-acre (6 ha) square, now a National Historic Landmark and the center of Downtown New Haven. New Haven is the home of Yale University. The university is an integral part of the city's economy, being New Haven's biggest taxpayer and employer. Health care (hospitals and biotechnology), professional services (legal, architectural, marketing, and engineering), financial services, and retail trade also help to form an economic base for the city. New Haven had the first public tree planting program in America, producing a canopy of mature trees (including some large elms) that gave New Haven the nickname "The Elm City".

Southampton is a major port and the closest city to the New Forest. It lies at the northernmost point of Southampton Water at the confluence of the River Test and River Itchen, with the River Hamble joining to the south of the urban area. The local authority is Southampton City Council, which is a unitary authority. Just over a quarter of the jobs available in the city are in the health and education sector. A further 19 per cent are property and other business and the third largest sector is wholesale and retail, which accounts for 16.2 percent. Between 1995 and 2004, the number of jobs in Southampton has increased by 18.5 per cent. Southampton has always been a port, and the docks have long been a major employer in the city. In particular, it is a port for cruise ships; its heyday was the first half of the 20th century, and in particular the inter-war years, when it handled almost half the passenger traffic of the UK. Today it remains home to luxury cruise ships, as well as being the largest freight port on the Channel coast and fourth largest UK port by tonnage, with several container terminals. Unlike some other ports, such as Liverpool, London, and Bristol, where industry and docks have largely moved out of the city centres leaving room for redevelopment, Southampton retains much of its inner-city industry.
