Canterbury Cathedral

The mother church of the Anglican Communion and one of England's oldest Christian sites, founded in 597. Archbishop Thomas Becket was murdered here in 1170, and it became one of the great pilgrimage destinations of medieval Europe, as told in Chaucer's Canterbury Tales. See the spot of the martyrdom, the medieval stained glass and the Norman crypt.

It's a UNESCO World Heritage Site with St Augustine's Abbey. Canterbury is about an hour by train from London; the old town is pleasant to walk around.
