As you walk into these oldest churches in Vienna, you will see a few unique things about each of them. The history is not so much different but what they host is quite distinct compared to other European cities. Let’s take a look at what we should look for in these churches.

Walking through Vienna is like turning the pages of a living history book. While the city does not possess the third- and fourth-century churches found in places like Rome or Naples, its nearly thousand-year-old churches reveal an equally fascinating story. Built after Vienna grew from a Roman military outpost into a thriving medieval city, these churches reflect the faith that shaped the capital of the Habsburg Empire. They invite visitors to explore how Christianity influenced Vienna’s history and continues to leave its mark on the city today.

Here is a path one can take that starts at some of the earliest churches near the Danube River and extends inland as the city developed.

One of my favorite things to do when I visit a new city is explore its oldest churches. I enjoy noticing their unique features, comparing them with churches I have visited elsewhere, and discovering what makes each one distinct. Even so, I know I miss details along the way. As I explored Vienna’s historic churches, I put together the following chart to help orient both myself and other readers.

Surprises in Vienna
My walk through Vienna brought several surprises. The first was how late the city’s historic churches appeared when compared with those of other European centers. After recently visiting Rome and Naples, where I explored churches dating to the third century, Vienna seemed to have developed much later. Curious about the reason, I did some research and discovered that Vienna began as a Roman military settlement and later grew into an important city. As the city expanded, its major churches followed.
I was also struck by the central role the Habsburg rulers played in building and supporting Vienna’s churches. Even more surprising, the remains of several emperors rest in different locations throughout the city. Their bodies lie in the Capuchin Crypt, their hearts in St. Augustine’s Church, and their internal organs in St. Stephen’s Cathedral. This unusual practice reminded me of Solomon’s famous judgment. He proposed dividing a living child to reveal the true mother, but wisdom ultimately spared the child. In contrast, the Habsburg tradition deliberately divided the remains of deceased rulers so that several important churches could preserve a connection to them. As an outsider, I find the custom fascinating, even if I struggle to understand the desire to keep a separate “piece” of a beloved emperor in different places.
Expectations on Visits
One aspect of Vienna impressed me above all: every historic church I visited remained open and active. Visitors can easily enter most churches, although crypts, catacombs, and special exhibits often require an admission fee. Because these churches continue to serve as places of worship, some areas were understandably inaccessible during services. Many also host concerts and evening musical performances, which adds another dimension to my visits. More than once, I discovered these events simply by stepping inside.
In this series on Vienna, I will briefly write about these churches and what I saw, including a Jewish site and visits to the Ephesus and Papyrus Museums near them.
Searching for St. Euphemia Basilica in Chalcedon
The history of Chalcedon often centers on the Basilica of St. Euphemia, the site of the Council of Chalcedon. Built over the grave of Saint Euphemia, this famous church has vanished from view, leaving behind one of the city’s greatest archaeological puzzles. Where did it stand? Historical sources, topography, and recent discoveries offer several compelling possibilities. Let us explore the leading theories.

Most people pass over the ancient ruins of Chalcedon without realizing what lies below. I have never walked through the archaeological site myself, but anyone can look down from the main bridge in Kadıköy, on Istanbul’s Asian side, and see what archaeologists have uncovered. From that vantage point, sacred apsidal structures, marble floors, and massive column bases begin to emerge from the earth. At first glance, they look like scattered stones. Yet each one tells part of the story of an important city. So what do these discoveries actually reveal?

Since 2018, archaeologists have uncovered remarkable new pieces of ancient Chalcedon. Excavations have revealed churches, graves, temples, and even an ancient harbor, offering fresh insight into this once-thriving city. With each new discovery, Chalcedon’s story becomes richer, but how much still lies hidden beneath the modern streets? What have archaeologists uncovered so far, and what discoveries might still await?

One of my favorite experiences in Ephesus is tracing the story of the early Church through the city’s changing landscape. I often pass by the multiple State Agora crosses, then enjoy the house church within the Terrace Houses before walking to the repurposed site of St. Mary’s Basilica, and finally, in Seljuk to St. John’s Basilica. Together, these locations reveal four distinct movements of church growth in Ephesus. As the city gradually expanded toward the Northeast, the Church also shifted with it, leaving behind a remarkable archaeological record of its development.
St. John’s Basilica eventually became the largest church in Asia Minor, while Hagia Sophia held that distinction in the eastern Roman capital of Constantinople. Let’s look beneath the surface to discover what makes this place truly unique.
