Ancient Churches | Ancient Church List

Many of the most fascinating historic sites on the planet are sacred and religious sites – among them are the ancient churches of the world which have survived to this day.

While many of the historical places we associate with Christianity are grand Cathedrals and inspiring churches, these historic sites tend to be medieval in their origin or of a more modern construction. To find ancient churches you have to look back to antiquity and explore those examples of ancient Roman or Greek era churches which have managed to survive intact.

This list of ancient churches can throw up examples which are quite different from the churches we are used to today. Rather than taking on the more standard church architecture which we recognise, many are in fact converted pagan temples or churches built from scratch by Roman engineers. And while some of these ancient churches have survived intact, others are simply the ruins of these intriguing early Christian places of worship.

Check out our ancient church list to explore more.
