Thomas Twining (1675-1741) founded the House of Twining by purchasing the original Tom's Coffee House at the back of the site in 1706, where he

introduced tea. In 1717 he opened the Golden Lyon here as a shop to sell tea and coffee.
In 1787 his grandson Richard Twining (1749-1824) built the handsome doorway incorporating his Grandfather's Golden Lyon symbol and two Chinese figures. Twinings is believed to be the oldest company to have traded continuously on the same site with the same family since its foundation.
In addition to the shop is a small museum at the rear, containing tea-related paraphenalia collected over the course of 300 years sales to the public. Amongst its exhibits is a wooden box displaying the initials T.I.P. – short for “To insure promptness”. Patrons of coffee houses, in which tea was first drunk in Britain, would drop a penny or two into the box, to encourage quick service. Where the modern phrase “tip” derives.
