During renovation works in 2009, Canterbury Archaeological Trust inspected the interior after it had been largely gutted. It seems an earlier phase of extensive renovations had already removed much of the early work. Three phases were evident, the last being modern in date. From the brickwork, the earliest part of the building is of 18th century date (the deeds suggest c.1720) an comprises the main west range, fronting onto the High Street, with a boundary wall extending to the east to enclose a rectangular plot that contained a well and probably out-houses. The south range was largely of 19th century date (c.1840) although traces of earlier brickwork at low level, extending eastwards from the rear of the main range, suggest the 19th century addition replaced a smaller, ground floor extension. Due to decay of the building's fabric, little of the 18th century fittings or features could be retained. A well was found in the rear courtyard, consisting of an 18th century brick lined shaft with chalk blocks lower down. Pottery recovered from the yard did not suggest direct waste disposal from the public house but did include material of 17th and 18th century date, along with 150 fragments of clay tobacco pipes. Of the dateable examples, 18 fall within the period 1640-1680 and most would seem to be 1660-1680. The remainder are all of later date, though there are no 19th century examples. (2)
