Wonderful 400-year old red brick and Surrey flint pub, which, in the 1840s, evolved from three former cottages, one of which was a former bakery. It was one of Caterham's early alehouses. It still retains three distinct areas; these are a front bar facing the main road which has the feel and character of a public bar, a high-ceilinged wooden-beamed middle room, with inglenook fireplace, where darts and cribbage are played, and a small lower-level rear area adjoining a rear patio garden. The name refers to Britain's only joint monarchy, William & Mary and a number of pictures of them adorn the walls. There is poker on Wednesdays and a quiz night on Thursdays. In addition to the three regulars, an extra beer, either a Fuller's seasonal beer or a guest from an independent brewery, is available. Each summer events such as Shakespeare in the Garden and Opera in the Garden are held as is live music usually 2 Saturdays a month.
