This charming and historical church, which is the oldest Roman Catholic church in the UK, is a sight to behold. Dating from the reign of Edward I, St. Etheldreda's was the town chapel for the Bishops of Ely, who had it built in the mid-13th century. It is named after the 7th-century East Anglian princess and Fenland saint, Etheldreda. During the Great Fire of London in 1666, St. Etheldreda's was luckily spared thanks to a sudden change in the wind direction.
