Document 6: History of the Port of Southampton: The Port of Southampton is a major passenger and cargo port located in the central part of the south coast of England. It has been an important port since the Roman occupation of Britain nearly two thousand years ago, and has a multifaceted history. From the Middle Ages to the end of the 20th century, it was a centre for naval shipbuilding and a departure point for soldiers going to war. The port also played a role in the development of hovercraft, flying boat services, seaplanes and the Spitfire fighter plane. Before the advent of jet travel, Southampton was Britain's gateway to the world. The port also played a minor role in the history of Britain's canals.
Document 7: Downtown Norfolk, Virginia: Similarly, the advent of newer suburban shopping destinations spelled demise for the fortunes of downtown's Granby Street commercial corridor, located just a few blocks inland from the waterfront. Granby Street traditionally played the role as the premiere shopping and gathering spot in the Hampton Roads region and numerous department stores such as Smith & Welton (1898-1988), Rices Nachmans (1918-1985) and Ames and Brownley (1898-1973), fine hotels and theaters once lined its sidewalks. However, new suburban shopping developments promised more convenience and comfort. The opening of Pembroke Mall in Virginia Beach, the region's first climate controlled shopping mall, and JANAF Shopping Center in Norfolk's Military Circle area, helped foment Granby Street's spiral into commercial obsolescence. With amenities such as ample free parking at the door of one's favorite store, and in the case of Pembroke Mall, climate control, the businesses of downtown's Granby Street found it harder and harder to compete.
Document 8: Fleetsbridge: Fleetsbridge is a small area of Poole, Dorset, centred on a busy gyratory and flyover. It lies north of Poole town centre and borders the neighbouring suburbs of Waterloo, Creekmoor, Oakdale and Canford Heath. The use of land varies between residential, retail and some light industry. The area is also home to Parkstone Grammar School when it moved there from Lower Parkstone in 1962. The site of the Tesco at Fleets Corner was, up until the 1980s, the home of Hamworthy Recreation Football Club before the land was sold and the club moved to Canford Magna on the northern extreme of the Borough of Poole. Opposite to Tesco, across Waterloo Road, is the home of the headquarters of the global company, Hamworthy Combustion Engineering. Fleets Industrial Estate lies to the south of the gyratory off Fleets Lane and is adjacent to Wessex Gate Retail Park, which has large retail outlets such as DFS, Currys and PC World.
Document 9: Southsea Hoverport: Southsea Hoverport is adjacent to Clarence Pier in the Southsea area of Portsmouth in southern England. From here frequent hovercraft services leave for Ryde on the Isle of Wight. The journey time is quicker than the conventional boats that sail from Gunwharf Quay, elsewhere in Portsmouth, but the hovercraft are more prone to service curtailment in inclement weather. Another problem are connections from here as when the service first started in the mid-20th century much of the land closer to Portsmouth and Southsea station was already occupied by both residential and naval units. To help alleviate this problem Stagecoach run the "Hoverbus" linking the terminal with Portsmouth and Southsea station and Portsmouth city centre. The nearest railway station is Portsmouth Harbour railway station, although Portsmouth and Southsea station is not much further away.
Document 10: Harbour Town: Harbour Town is a shopping centre concept that incorporates multiple factory outlets in one centre. The centres especially popular with locals and tourists.

Document 11: Pentagon Shopping Centre: The Pentagon Shopping Centre (known locally as 'The Pentagon') is a shopping centre in Chatham in Kent.

The shopping centre contains over 70 shops and 7 leisure facilities, many high street names in fashion, homeware and food stores. There are also cafes, restaurants and a bowling alley. As is common with some other 1970's era town centre shopping centres, The Pentagon does not feature a food court or any dedicated dining area. Instead, there are various food outlets scattered throughout the centre. Built as part of the redevelopment of Chatham town centre in the 1970s, the Pentagon also features the high rise Mountbatten House office block, which has controversially stood empty or part-used for most of its history. The Pentagon, Mountbatten House and the Brook multi-storey carpark are built in a distinctive orange-red brick with grey concrete.
Document 12: Newport (Isle of Wight) bus station: Newport bus station, on the Isle of Wight is located at Orchard Street in Newport town centre. Recent redevelopment has seen the former 1960s-built South Street bus station demolished, to make way for a new row of shops, and the current facility built behind that site. Newport is used as the hub of Southern Vectis's network of bus routes, so the majority of routes use Newport bus station, currently 11 out of 14. On 1 July 2007 the bus station became a no smoking area in its entirety.

Later known as HMS "Vernon", the military site closed in 1995, and opened to the public as Gunwharf Quays after six years of reconstruction (which included the restoration of some of the surviving 18th and 19th-century Gun Wharf buildings). The landmark Spinnaker Tower, which also stands on the site, was opened a few years later.
