Fortnum & Mason, often shortened to just "Fortnum's" is a department store and Royal Warrant holder, situated in central London, with two other branches in Japan. Its headquarters is located at 181 Piccadilly, where it was established in 1707 by William Fortnum and Hugh Mason. It is privately owned by Wittington Investments Ltd. Fortnum and Mason is recognised internationally for its high quality goods and as an iconic British symbol. It has held many Royal Warrants over the past 150 years. Founded as a grocery store, Fortnum's reputation was built on supplying quality food, and saw rapid growth throughout the Victorian era. A venture into the US in the 1930s ended in failure, with the company's flagship store on Madison Avenue closing almost as soon as it opened. Though Fortnum's developed into a department store, it continues to focus on stocking a variety of exotic, speciality and also 'basic' provisions. It is also the location of a celebrated tea shop.
