Heraldry developed from the need to identify people, particularly in battle.   A simple form is the flag of St. George.   Over the centuries it became complex, with a coat of arms showing the status of the individual and his family.

The most obvious examples of heraldry in St. Wulfram's are the hatchments on the south wall and the the Royal Arms of Elizabeth I (the earliest in Lincoln diocese, we believe), Charles II and Elizabeth II.

Memorials also display heraldic devices
