Sheffield is a city in South Yorkshire, England, named from the river Sheaf that flows through it. Sheffield’s administrative centre is located in the city. The city is located in the eastern Pennine foothills and valleys of the river Don, which has four tributaries: the Loxley, the Porter Brook, the Rivelin, and the Sheaf. Sixty-one percent of Sheffield has green space, and one-third of the city is located inside the Peak District national park. There are around 250 parks, forests, and gardens throughout the city, with an estimated 4.5 million trees. The city is located 29 miles south of Leeds, 32 miles east of Manchester, and 33 miles north of Nottingham.

Sheffield played an important part in the Industrial Revolution, producing several major inventions and technology. When stainless steel and crucible steel were invented locally in the nineteenth century, the city’s traditional cutlery trade expanded dramatically, fuelling an almost tenfold growth in population. Sheffield F.C., the world’s oldest football club, and Sandygate, the world’s oldest football ground, are both located in the city. The Steel City derby refers to matches between the two professional clubs, Sheffield United and Sheffield Wednesday. The World Snooker Championship and the Sheffield Steelers, the UK’s first professional ice hockey team, are also held in the city.

Despite being a city, is colloquially characterized as „the largest village in England“ due to a mix of geographical remoteness and demographic stability. It is geographically secluded, separated from the rest of the world by a ring of hills. Sheffield, according to mythology, was built „on seven hills“ like Rome. Its surrounding terrain proved unsuited for industrial development and is now home to various protected green belt areas. These geographical limitations have hampered urban expansion, resulting in a relatively steady population size and little mobility.
