The image is a blue plaque on a stone wall. The plaque is circular in shape and has white text on it. The text reads "Howden Civic Society Grammar School" and "A school was established within the Minister in about 1265, teaching Latin (the language of public administration) to all pupils from 6-18 years, and Song to the choristers. The present two schoolrooms date from Tudor times and were in use until 1925. It was one of the last endowed schools in East Yorkshire. Supported by the Heritage Lottery Fund."
