Fortnum & Mason (colloquially often shortened to just "Fortnum's") is an upmarket department store in Piccadilly, London, with additional stores at St Pancras railway station and Heathrow Airport in London, as well as various stockists worldwide. Its headquarters are located at 181 Piccadilly, where it was established in 1707 by William Fortnum and Hugh Mason. Today, it is privately owned by Wittington Investments Ltd. Founded as a grocery store, Fortnum's reputation was built on supplying quality food, and saw rapid growth throughout the Victorian era. Though Fortnum's developed into a department store, it continues to focus on stocking a variety of exotic, speciality and also 'basic' provisions. The store has since opened several other departments, such as the Gentlemen's department on the third floor. It is also the location of a tea shop and several restaurants.
