Rugby School -  Rugby School is a co-educational day and boarding school located in the town of Rugby Warwickshire England. Rugby School is a registered charity #528752 and is one of the oldest independent schools in Britain. The influence of Rugby and its pupils and masters in the nineteenth century was enormous and in many ways the stereotype of the English public school is a reworking of Thomas Arnold's Rugby[citation needed]. It is one of the best-known and most expensive schools in the country.
