A large circular oven was excavated close to the northern boundary of the site at Butt Road (feature HF27). The oven was 2m in diameter, with foundations of daub and rubble, mainly broken tile, greensand, flint and septaria, laid on a rectangular bed of clay measuring about 3.5m by 3m. The lower part of the oven wall was of daub reinforced in places with tile fragments and rubble. No definitive dating evidence was recovered, but from the layer of charcoal at the mouth of the oven came a single sherd dated to the 13th-14th century, and several sherds of similar date derived from the material above the oven. <1>
