Motto: 'CIVITAS LINCOLNIA', the motto 'FLOREAT LINDUM' is also sometimes used.
The arms were never officially granted, but are recorded at the College of Arms.
The arms date from at least the 14th century. The cross is most likely derived from the Diocese of Lincoln. The fleur-de-lis is the symbol for the St. Mary, patron saint of the city. The St. Mary also appeared on the oldest known seal of the city, known from around 1300.
