After the murder of Archbishop Thomas Becket in Canterbury Cathedral in 1170, the shrine that grew around his tomb became the most important pilgrimage destination in medieval England — the very journey Geoffrey Chaucer frames in The Canterbury Tales. Rebuilt in soaring Gothic style after a fire in 1174, the cathedral's choir and later nave show off the ribbed vaulting that let masons open up huge window expanses for stained glass while carrying the roof's weight down through slender piers.
Canterbury Cathedral, along with St Augustine's Abbey and St Martin's Church, was inscribed as a UNESCO World Heritage Site in 1988. The Pilgrims' Way, an ancient trackway along the North Downs, roughly follows a route pilgrims may have used travelling from Winchester to Canterbury.

How Gothic ribbed vaulting channels the roof's weight down through piers to open up walls for stained glass, and how the real-world distances of medieval approach roads shaped how long a pilgrimage to Canterbury actually took.
Switch between the nave interior and the city map, pick a pilgrim route to see its distance and travel time, and adjust party size, walking speed and time of day to change the light raking through the vault.
Canterbury Cathedral was inscribed as a UNESCO World Heritage Site in 1988, and the ancient Pilgrims' Way along the North Downs still roughly traces one of the routes travellers used to reach Becket's shrine.
