Hadrian's Wall, Heddon on the Wall, UK

A short section of Hadrian's Wall at the west end of a length of preserved Wall about 255m long, consolidated and in the care of English Heritage, just east of Heddon on the Wall village. This represents a part of the planned 'broad wall'; further west the structure was reduced in thickness to save time and resources. The broad wall at Heddon is between 2.8m and 3m wide and up to 1.7m (7 courses) high. The rubble core was originally set in puddled clay, but was reset in mortar to preserve the section when it was consolidated. The first 12m at the west end has only the outer face exposed. At the west end (NZ 13622 66942) a circular kiln was built into the wall in medieval times, probably to dry corn. It measures 1.9 m in diameter, has a paved floor, and the surrounding wall has a maximum height of 0.7 m (3 courses). The flue is in the south-west arc and is 1.4 m wide.
