Religion is as old as history itself. Of the Earth’s many religions, the largest faith is Christianity, which has around 2.4 billion followers across the globe. That is roughly a third of the world’s population! Since the origins of Christianity during the 1st century CE, there have been countless places of worship built or converted to serve as a Christian church. Many of these structures still stand today, some of which are actually still in use! The team at AAA State of Play has created this visual guide to showcase the oldest churches in the world and the stories behind them:

What is the oldest church in the world?

While there are differing archaeological perspectives on the oldest churches in the world, it is believed that the Megiddo church near Tel Megiddo, Israel is the oldest purpose-built church in the world. Today, the remnants of Megiddo church are located on the grounds of the Megiddo Prison, where they were discovered in late 2005 by an inmate. How old is the Megiddo church? Archaeologists uncovered coins, pottery, and inscriptions that date it back to circa 230 CE, which is nearly 1,800 years ago! The purposeful covering of mosaics suggests that the site was abandoned around 305 CE, which correlates with the crisis of 303 CE, when Christian communities were severely prosecuted by the Roman Empire during what was known as the Diocletianic Persecution. Fortunately, hiding the mosaics also helped to preserve them. The mosaics in the oldest Christian prayer house are significant because it is the first known archaeological evidence of believers in the divinity of Jesus Christ. One of the mosaics reads: “to the God Jesus Christ” and also contains images of fish, an early Christian symbol.

Why is Megiddo important?

What is the biblical significance of Megiddo, the name of this church? According to Eric Cline, a professor of classical and Near Eastern languages and civilizations, Megiddo is heralded by the New Testament as the setting for the penultimate battle between the forces of good and evil, or as it is better known, Armageddon. In fact, the word “Armageddon” comes from “Har Megiddo,” which is Hebrew for “mountain of Megiddo.” There is some poetic beauty in that the oldest church on Earth is also prophesied as the location for the battle to end all battles. However, there has been some debate among archaeologists and anthropologists regarding the authenticity of this claim. Anthropologist Joe Zias, a former curator for the Israel Antiquities Authority, stated: “My gut feeling is that we are looking at a Roman building that may have been converted to a church at a later date." Regardless, the Israel Postal Service issued a 15-shekel stamp featuring the fish mosaic preserved on the church foundation to honor the discovery.

Oldest Depiction of Jesus

We discussed the earliest surviving mention of Jesus as divine, but what about the earliest images of Jesus? The oldest-known Christian paintings are believed to be the frescoes preserved on the walls of the Dura-Europos church, the earliest identified Christian house church (an ordinary home converted into a place of worship). One of these paintings, “Christ Healing the Paralytic,” depicts the first known visualization of Christ performing a miracle.

Is the Pantheon the oldest church in the world?

Yes and no. You may have noticed that we have listed the Pantheon as the oldest church in the world, which is true in the sense that it is the oldest building in the world that is currently a church and it is also the oldest building in the world dedicated to worship. What was the original purpose of the Pantheon? It is believed that the Pantheon was originally designed around 25 CE by statesman Marcus Agrippa (son-in-law of the first Roman emperor, Augustus) as a temple for the Roman gods. The temple’s name is derived from the Greek words pan, meaning “all,” and theos, meaning “gods.”

What is the Pantheon used for today? The Pantheon now serves as a Catholic church dedicated to St. Mary and the Martyrs. When did the Pantheon become a church? The Pantheon was gifted to the Catholic Church in 609 CE by Emperor Phocas. While most of the exterior and interior marble decoration was left untouched, all of the pagan sculptures were removed from the inside. So in a sense, it is the oldest Catholic church, it just happens to have a colorful history!

What is the oldest cathedral in the world?

The oldest cathedral of all time is widely regarded to be the Etchmiadzin Cathedral in Etchmiadzin/Vagharshapat, Armenia, which was built in 301 CE by Armenia’s patron saint Gregory the Illuminator to honor the adoption of Christianity by King Tiridates III. The cathedral was built over the ruins of a pagan temple to symbolize this conversion.

Where is the oldest site of continuous worship in Christianity?

The oldest site continuously used as a place of worship in Christianity is the nativity grotto where The Church of the Nativity in Bethlehem, Palestine was built. The grotto is profoundly significant to various Christian denominations as the birthplace of Jesus Christ. Emperor Constantine the Great commissioned the construction of the Church of the Nativity in 326 CE upon this holy site. In 2012, the Church of the Nativity was designated as a World Heritage Site and was the first to be listed by UNESCO under ‘Palestine.’ The basilica is also one of the oldest churches in the Holy Land.

Playgrounds for churches

While we cannot compare to history’s greatest architects who built the world’s oldest churches, the team at AAAStateofPlay is proud to have constructed many high-quality, customized church playgrounds and other playground projects across the United States. For example, check out the playground we built for St. Paul’s Episcopal Church in our hometown of Indianapolis, Indiana! We customized the color palette and design so that it harmonized with the church’s aesthetic and ensured that children of all ages and abilities would be able to enjoy it. If you’re looking for affordable church playground equipment, give us a call at 1-877-826-2776. Pray and play all day!
