J. Hatchard and Son
Hatchards is an English bookshop claiming to be the oldest in the United Kingdom, founded on Piccadilly in 1797 by John Hatchard. After one move, it has been at the same location on Piccadilly next to Fortnum & Mason since 1801, and the two stores are also neighbours in St Pancras railway station as of 2014. It has a reputation for attracting high-profile authors and holds a royal warrant, granted by King Charles III.
