Our fair city has links to the legend of Robin Hood and to the lace-making, bicycle (notably Raleigh bikes), and tobacco industries.

It was granted its city charter in 1897 as part of Queen Victoria's Diamond Jubilee celebrations. Nottingham is a tourist destination; in 2011, visitors spent over £1.5 billion—the thirteenth-highest amount in England's 111 statistical territories.

In 2017, Nottingham had an estimated population of 329,200. It is the largest urban area in the East Midlands and the second-largest in The Midlands. 

Nottingham has an award-winning public transport system, including the largest publicly owned bus network in England and is also served by Nottingham railway station and the modern Nottingham Express Transit tram system.

It is also a major sporting centre, and in October 2015, was named 'Home of English Sport'. The National Ice Centre, Holme Pierrepont National Watersports Centre, and Trent Bridge international cricket ground are all based in or around the city, which is also the home of two professional league football teams; the world's oldest professional league club Notts County, and Nottingham Forest, famously two-time winners of the UEFA European Cup under Brian Clough in 1979 and 1980.

The city also has professional rugby, ice hockey and cricket teams, and the Aegon Nottingham Open, an international tennis tournament on the ATP and WTA tours. This accolade came just over a year after Nottingham was named as the UK's first City of Football.

On 11 December 2015, Nottingham was named a "City of Literature" by UNESCO, joining Dublin, Edinburgh, Melbourne and Prague as one of only a handful in the world. The title reflects Nottingham's literary heritage, with Lord Byron, D. H. Lawrence and Alan Sillitoe having links to the city, as well as a contemporary literary community, a publishing industry and a poetry scene.

The city is home to two universities - Nottingham Trent University and the University of Nottingham.

Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives.

Under normal conditions nitrogen is a colourless, odourless and tasteless gas.

Nitrogen makes up around 78% of the air we breathe.

Nitrogen is present in all living things, including the human body and plants.
