The town grew up from Anglo-Saxon times around a palace belonging to the Archbishop of Canterbury. In 1276 the archbishop allowed a weekly market to take place nearby and this date is taken as the founding of the town. The town grew in the eighteenth century as a stage coach stop on the way to the popular seaside town of Brighton from London. In the nineteenth century railways put the town only 15 minutes from London by fast train and it grew 23 times in terms of the number of people living there between 1801 and 1901.
