Grantchester is a village on the River Cam or Granta in Cambridgeshire, England, close to Cambridge. It is listed in the Domesday Book (1086) as Grantesete and Grauntsethe. Grantchester is mentioned briefly in book IV, chapter 19 of Bede's Ecclesiastical History of the English People. John de Grauntsete, a lawyer who had a highly successful career as a judge in Ireland, was born in Granchester c.1270.
Grantchester is said to have the world's highest concentration of Nobel Prize winners, most of these presumably being current or retired academics from the nearby University of Cambridge. Grantchester has been home, since 1969, of the sculptor Helaine Blumenfeld OBE.
Students and tourists often travel from Cambridge by punt to picnic in the meadows or take tea at The Orchard. In 1897, a group of Cambridge students persuaded the owner of Orchard House to serve them tea in its apple orchard, and this became a regular practice. Lodgers at Orchard House included the Edwardian poet Rupert Brooke, who later moved next door to the Old Vicarage. In 1912, while in Berlin, he wrote a poem of homesickness entitled "The Old Vicarage, Grantchester". The house is currently the home of the Cambridge scientist Mary Archer and her husband, Jeffrey Archer.
The footpath to Cambridge that runs beside Grantchester Meadows is nicknamed the Grantchester Grind. Grantchester Grind is the title of a 1995 comic novel written by Tom Sharpe. Further upstream is Byron's Pool, named after Lord Byron, who is said (by Brooke, at least) to have swum there. The pool is now below a modern weir where the Bourn Brook flows into the River Cam. Byron's Pool is a Local Nature Reserve.
