15 Biggest Churches in The World

Are you involved in architecture and now you are curious about the biggest churches in the world?  We were interested in it too, so we prepared this article.  As for me who am a Protestant theologian, churches are always an interesting subject to study, read and speak about it. Nevertheless, so far I haven’t known too much about the largest churches in the world myself either, so it was a pretty nice experience for me, too. Actually, when we say ‘church’, it means a Christian building, as speaking about other religions we use the terms such as mosque, synagogue, etc. It is important to mention that many times when we consider biggest churches or churches at all in the world, we think of only medieval buildings or older ones. But as a matter of fact, there are modern churches built nowadays as well, and what is really surprising is that they are kind of big! Not only chapels or something like that but huge churches like Church of the Most Holy Trinity in Portugal which was finished only ten years ago!

15 Biggest Churches in The World

If you would like to know more about the different types of religions you can do it by reading 11 Most Popular Religions in the World. Humans’ life has always been related to religions as at the very beginning people could explain natural things that happened with supernatural powers committed by different gods. Nowadays we can observe the vivid diversity of religions.

Our methodology was to find the measures of the churches in the world and compare them with each other. Comparing itself was not an easy task as an accepted measure of largeness can include volume, area, height, width, and capacity but this latter is rather a subjective aspect. So we do emphasize that one church can be declared to be the largest concerning one point of view (for example area as we made the comparison) but on the other hand, regarding another aspect, there can be a much larger one. We can find churches that have equal claim to be the largest but so far official body governing hasn’t been set up over this issue, and general criterion hasn’t been declared – consequently any kind of comparison you can find is pretty subjective. Now you can read ours as we investigated which are the biggest churches in the world regarding their area. At first, we checked the thirty largest churches in the world on Guinness Records then we narrowed the number for only 15 by listing them by the area. For narrowing, we used the sites of each church to gain all the necessary data and also got useful information about Medieval Churches In The World. Now you can see the churches ranked more or less objectively, but what is sure if you are fond of architecture you will enjoy this list!

15. Basilica of Our Lady of Guadalupe, Mexico City, Mexico

This church got the fifteenth place in our list with its large measure of 8,167 m2, but if you feel that is extremely big you will be shown much-much bigger ones now! It was built from 1974 to 1976 and its diameter is amazing 102 m! Roman Catholic believers go here to adore the Lord.

Ulm Minster was originally devoted to the Roman Catholic Church that’s why its construction began in 1377.

With its 8,300 m2 of the area, it is the twelfth biggest church in the world on our list of biggest churches in the world. Its construction started in 1296 and ended in 1436, so it lasted for 140 years! As we can see the incredible year of beginning, we can claim that this church is the oldest one in our list, but not the oldest one in the world. With its early starting, it is the tenth most ancient one. The world’s largest brick and mortar dome belongs to it.

If we think of the biggest churches in the world, we often think that they must be very old buildings and that nowadays monumental churches aren’t built anymore. But, that is not true!

15 Biggest Churches in The World2. Basilica of the National Shrine of Our Lady of Aparecida, Aparecida, Brazil, South-America

This church also has outstanding measures but they were enough for only the second place on our list of biggest churches in the world.

15 Biggest Churches in The World1. Saint Peter’s Basilica, Vatican City, Vatican City, Europe

Who hasn’t heard of the most famous Basilica in the world? Without a shadow of a doubt, the most monumental church in the world is St. Peter’s Basilica. Its interior area covers 15,160 m2; it was built from 1506 to 1626. The heart of the Roman Catholic Church, as it is often called, is visited by millions of tourists every year.
