Examination of the new G.P.O site on Head Street before building work began. A broad band of land along the east side of the area, bordering Head Street had been severely disrupted by a series of cellars belonging to the old buildings. Behind this other areas were inaccessible due to extensive dumps of building material but an E-W trench was cut across the centre of the site. The maximum depth of excavation was 8ft below which the pottery was entirely Roman but with no notable stratification. At the west end of the trench the remains of Roman walls led to the discovery of a semicircular masonry structure lying 6ft 6in from the surface. A second trench was cut northwards and west of the cellars, and a third was dug towards the NW corner of the site where a red tessellated pavement was found alongside further masonry remains. <1>
