Whatever version takes your fancy [or none] she was being venerated as a Saint by the beginning of the 11th century. John, the Oxford carpenter in Chaucer's Miller's Tale invokes her as his saint. This is her shrine in its present form.
It has had a somewhat chequered history. Built originally in 1289 it was then destroyed during the Reformation. Over time pieces have been rediscovered and it has been rebuilt. The base is original and shows Frideswide hiding in the forest but the rest consists of later additions. When first built it would have been brightly coloured. However, today it is covered with several curious foliate faces.
This is a modern depiction of the saint made from a railway sleeper and a detail from the Burne-Jones window behind the shrine which shows her ascending into heaven in a boat.
Her saint day is 19th October which is supposedly the date of her death. Her remains are believed to be buried within the church floor but the exact location is unknown.
