The arms were officially granted on June 12, 1934.

The shield has devices which symbolise the parishes that made up the borough. These are represented by the lamb and the flag, a Maltese cross, the crossed keys of St. Peter, cross of St Andrew and the sword of St Paul.

The crest and dexter supporter refer to the fame brought to the town by the comic opera, The Pirates Of Penzance, by Gilbert and Sullivan. The sinister supporter is a fisherman, similar to that found in the Cornwall County Council arms.

The Latin motto means "For the reward of the good and the dread and terror of the bad" and is taken the town's charter.

Before 1934 the city only used a seal with the head of St. John on a platter, see below.
