One of the first and one of the best of the church finding websites.
Most churches are listed although some have not entered a great deal of detail about themselves. The churches at the top of the list have the fullest entries. You will need to click FOR MORE for the rest.
You should have no trouble finding churches within the Cambridge area.
'Church Near You' is a Church of England directory but other denominations can also register free. Entries go from a basic name and address to comprehensive details about the churches listed. However very many churches are not listed at all so you may need to go to Find A Church to see more churches around the Cambridge area.
The Thompson guide lists places of worship for every denomination, creed and faith. You just see the name and address plus an email button in some cases. The Thompson guide has truely excellent maps!
