A town crier is a person who is employed by a town council to make public announcements in the streets. The crier can also be used in court or official announcements. Criers often dress elaborately, a tradition known from the 18th century, in a red and gold robe, white breeches, black boots and a tricorne hat.

They carry a handbell to make a loud noise and they shout the words "Oyez, Oyez, Oyez!" before making their announcements. The word "Oyez" means "hear ye," which is a call for silence and attention. Oyez is from an Anglo-Norman word for listen. Some town criers announcements are recorded in books called a Proclamation Book The proclamations book in Chester from the early 19th century records the town criers call as "O Yes, O Yes!"
