(Glossary of Heraldic Terms)
The lion depicts St John's status as the provincial capital and seat of the Lieutenant-Governor. The mural crown is commonly found in the arms of fortified cities, and makes particular reference to the Battery. The rocky mount upon which the lion stands refers to the "Rock" of Newfoundland and to the dominant topography of the capital region. The badge's field, like that of both the provincial and civic arms of St. John's, is red.
