A roundel is a circular charge in heraldry. Roundels are among the oldest charges used in coats of arms, dating from the start of the age of heraldry in Europe, circa 1200–1215. Roundels are typically a solid colour but may be charged with an item or be any of the furs used in heraldry. Roundels are similar to the annulet, which some heralds would refer to as a false roundel.[1]
Plural are termed pomeis.
