The Itineraries of William Wey is a 15th century pilgrimage account to the Holy Land that offers insights into travel, religious faith and the topography of Medieval Europe. Wey, a Devon priest was granted special dispensation by Henry VI to go on length pilgrimages. Perhaps the first known travel guide, his book has been described as the original ‘Rough Guide for Pilgrims’.
