I have compiled the most comprehensive and accurate map to date of Church congregations in the United Kingdom and Republic of Ireland. This is viewable through the Google Earth application; which is a free download available from Google.
It contains the exact location of almost every congregation, whether they meet in a purpose built chapel or rented building, along with a photo in most cases, addresses, telephone numbers and meeting times. It also indicates Family History Centres.
The file has many other features worth looking at; just click on the folders and many sub-folders in the 'Places' pane on the left-hand side of the browser to see what I mean.
This is a work in progress and updates are being periodically made. Feel free to make any suggestions about how it could be improved.
One extra feature for those who have purchased Google Earth Pro and posess a GPS device such as a Sat Nav can download the file onto the device for directions to any Church meeting place in the UK and Ireland, though as I'm too poor to posses either I've not been able to test that function out.
Try it out before you download (reduced features and functionality):
