An abortive excavation was undertaken by the Morant Club in search of the castle ditch and forum wall. A single trench was cut northwards from the north kerb of High Street, on the site of the War Memorial, opposite All Saints Church. The trench measured 15 ft 10 in deep at the south end and 17 ft. at a point 21 ft. north of this. The trench was largely interrupted by old cellars. At the south end of the trench was a deposit of made soil lying over a bed of yellow clay which was believed to be the foundation of a Roman street along the High Street. The clay lay over natural sand. Elsewhere in the trench was found the remains of what was believed to be Norman wall.<1> Work on the site was begun in December following demolition of the buildings on the site. The work was directed by P.G. Laver. A draft report was completed during March 1922. The section 'merely served to indicate, in part by inference, the width and location of the ditch and showing it to be c.6.5 m deep from modern ground level.<2> Hull believed that the trench had been cut across the Norman ditch of the castle near its south east corner and that the wall was in fact Roman.<3> The wall was probably that of the Temple Precinct (see MON713; MCC1544).
