When the borough was created in 1900, the corporation adopted a seal which was used in place of a coat of arms. The device was derived from that of the borough's forerunner, Lambeth Vestry. At the base of the seal was a lamb, a play on the name "Lambeth", and a symbol long used to represent the parish. The two shields were those of the Diocese of Canterbury and the Duchy of Cornwall. The first referred to Lambeth Palace, residence of the Archbishop of Canterbury. The second was to show that the Duchy owned estates in the Kennington area of the borough. The design was completed by the cypher of Queen Victoria, and the year of the borough's founding. This device can still be seen in the circular hall of Lambeth Town Hall.
