Gules three Seaxes fessewise in pale Argent pomels and hilts Or points to the sinister and cutting edges upwards.
Origin/meaning
The arms were officially granted on 15 July 1932.
The arms are those attributed to the ancient Kingdom of the East Saxons. These were regarded as the county arms long before the official grant.
They were also used by Middlesex until they added a saxon crown to the design. The swords are distinctive notched seaxes, and thus an allusion to the word Saxon.
