The quest to uncover the nation's favourite churches is part of the National Churches Trust's 60th anniversary.
The National Churches Trust is also inviting members of the public to nominate their favourite churches via Twitter using the hashtag #favouritechurch or posting a message on Facebook.
The fun campaign has a serious message behind it as the trust hopes to raise greater awareness of the fact that churches are some of the UK's best loved buildings and need continued funding if they are to be preserved for future generations to enjoy.
Claire Walker, chief executive of the National Churches Trust said: "The UK's 47,000 churches, chapels and meeting houses are a tremendous asset to the nation. Together, they form an unparalleled network of public buildings which sustain local communities.
"'The UK's Favourite Churches' is a celebration of some of our most loved and interesting places of worship. Over the summer holidays, I hope more people will discover the joys of visiting churches and seek out some of the churches chosen. There is plenty to see and much history to be discovered."
"When people do visit a church, I hope they will bear in mind that keeping churches, chapels and meeting houses looking beautiful, and able to cope with the demands of the 21st century, costs money.
"Replacing a leaking roof, fixing a leaning spire or repairing precious medieval stonework can cost many hundreds of thousands of pounds - which is much more than most church congregations can afford."
