The arms consisted of a red shield bearing a silver triple-towered castle with a gold ancient crown over the central tower.

The design was taken from the earliest surviving seal of the borough dating from the twelfth century, which showed a castellated gateway over which appeared a crowned head, believed to be that of Henry I.

The arms were blazoned as follows:[6] Gules a castle with three towers Argent surmounted by a crown composed of fleurs-de-lys Or; and for the Crest: on a wreath of the colours, in front of a king's head affrontée, couped below the shoulder proper, vested Gules, crowned and crined Or, a lion couchant gurdant Or; and for Supporters: on either side a lion Or holding in the exterior paw a branch of mountain ash proper.The design on a seal adopted in the seventeenth century was used in lieu of arms until 1922.

The building had been the earliest meeting place for the borough corporation, and featured a belfry and a market cross.
