Festivals and events Several fairs and festivals take place in Cambridge, mostly during the British summer. Midsummer Fair dates back to 1211, when it was granted a charter by King John. Today it exists primarily as an annual funfair with the vestige of a market attached and is held over several days around or close to midsummers day. On the first Saturday in June Midsummer Common is the site for Strawberry Fair, a free music and children's fair, with various market stalls. For one week in May, on Jesus Green, the annual Cambridge Beer Festival has been held since 1974. Cambridge Folk Festival is held annually in the grounds of Cherry Hinton Hall. The festival has been organised by the city council since its inception in 1964. The Cambridge Summer Music Festival is an annual festival of classical music, held in the university's colleges and chapels. The Cambridge Shakespeare Festival is an eight-week season of open-air performances of the works of William Shakespeare, held in the gardens of various colleges of the university.

The Cambridge Science Festival, typically held annually in March, is the United Kingdom's largest free science festival. The Cambridge Literary Festival, which focusses on contemporary literary fiction and non-fiction, is held bi-annually in April and November.
