Archaeologists working in northern Iraq have uncovered a 1,500‑year‑old religious complex that is forcing scholars to rethink when and how different faiths managed to live side by side. At a site called Gird‑î Kazhaw, evidence of Christians, Zoroastrians and later Muslims sharing the same landscape suggests that everyday coexistence was more common, and began earlier, than many written sources imply. The finds point to a rural world where religious boundaries were porous, negotiated in mudbrick and rammed earth rather than decreed only in royal edicts.
Instead of a single dominant faith stamping out rivals, the layers at Gird‑î Kazhaw show a village adapting as empires and religions shifted around it. I see in this excavation a rare, ground‑level view of how ordinary believers in late antique Iraq navigated overlapping sacred spaces, from a church‑like hall to Zoroastrian fire rituals and, later, Islamic practices, all within the same broader settlement.
A quiet hill in Iraq that upends the textbook story
Gird‑î Kazhaw sits in the rolling countryside of northern Iraq, far from the monumental capitals that usually dominate histories of late antiquity. For years it was just another low mound in a landscape dotted with tells, the kind of place that rarely makes it into sweeping narratives about empires and faith. Excavations have now revealed that this unassuming hill once held a complex where Christians and Zoroastrians, and eventually Muslims, moved through the same terrain, leaving behind architecture, ceramics and ritual traces that overlap rather than replace one another. The very ordinariness of the site is what makes it so disruptive to long‑held assumptions about religious rivalry.
Instead of a clean sequence in which one faith triumphs and erases the material presence of the previous one, the stratigraphy at Gird‑î Kazhaw shows continuity of settlement as religious identities shifted. Archaeologists have traced how Christians and Zoroastrians shared the same rural landscape, with later Islamic layers adding yet another chapter to the mound’s story, a pattern that directly challenges the idea that conversion always meant abrupt rupture. The emerging picture, described in detail in reports on the archeological findings in Gird‑î Kazhaw, is of a community that adjusted to new religious currents while keeping its settlement and many daily routines intact.
The 1,500‑year‑old church‑like hall at the heart of the story
At the core of the new interpretation is a 1,500‑year‑old building that looks, in plan and fittings, very much like a church. The structure, uncovered by a research team from Goethe University Frankfurt, includes a hall layout and internal features that align with known Christian worship spaces from late antique Mesopotamia. Its orientation, the arrangement of entrances and the likely placement of liturgical furnishings all point to Christian use, even though the building sits in a rural village rather than a bishop’s city. This alone expands the map of where Christian communities were active in northern Iraq during the Sasanian period.
What makes the hall even more significant is its context. The Goethe University Frankfurt team did not find it in isolation but as part of a broader settlement where other religious practices also left their mark. The building’s Christian character is supported by architectural parallels and by finds that indicate liturgical activity, yet it coexisted with spaces that can be linked to Zoroastrian ritual, suggesting that the villagers did not live in a neatly segregated religious quarter. The excavation reports from Goethe University Frankfurt’s work in northern Iraq emphasize how this church‑like structure anchors a more complex story of shared space than scholars previously expected in a Sasanian‑ruled countryside.
Material proof that Christians and Zoroastrians shared a village
For decades, historians have debated whether Christians and Zoroastrians in the Sasanian world mostly clashed, coexisted at arm’s length or blended practices on the ground. Gird‑î Kazhaw finally offers hard material evidence that at least in one northern Iraqi village, Christians and Zoroastrians lived in close proximity and navigated each other’s presence without erasing it. Archaeologists have identified installations and finds that point to Zoroastrian fire rituals alongside the Christian hall, indicating that the same settlement hosted both communities. This is not just a matter of overlapping timelines in texts but of physical spaces that were used and reused by people who knew their neighbors followed a different faith.
The project, part of a broader investigation into Rural Settlements of the Sasanian Period, has documented architectural features and artifacts that together form what the team describes as evidence of Christian Zoroastrian coexistence in northern Iraq. The combination of a church‑like building with other structures and deposits that fit Zoroastrian ritual practice gives scholars a rare, multi‑layered snapshot of religious life outside the imperial capitals. Reports on the evidence of Christian Zoroastrian coexistence highlight how this mix of material indicators, including clear signs of Christian use, moves the discussion beyond speculation based only on later chronicles.
Why a small Sasanian village matters more than imperial capitals
Most histories of late antique religion in Mesopotamia focus on royal courts, metropolitan sees and monumental fire temples, which naturally foreground conflict and official policy. By contrast, Gird‑î Kazhaw was a small rural settlement, the kind of place that rarely appears in written sources but quietly sustained the empires that ruled over it. Archaeologists involved in the project argue that this emphasis on capitals and major cities has long obscured the essential economic and cultural role played by villages, where farmers, artisans and local elites negotiated religious change in more pragmatic ways. In a village like this, the pressure to keep fields productive and water flowing may have outweighed the urge to draw hard confessional lines.
That shift in focus is central to the interpretation advanced by Tamm and Wicke, who contend that the rural record shows how religious identities could be layered and flexible over generations. They suggest that in places like Gird‑î Kazhaw, the balance between Christian and Zoroastrian practices may have changed gradually, with buildings repurposed and rituals adapted rather than abruptly replaced. For archaeologists and historians alike, the patterns visible in the soil today offer a counterweight to polemical texts that present conversion as a zero‑sum contest. The argument by Tamm and Wicke that smaller villages carried an essential economic and cultural role, and that religious use may have shifted over generations, helps explain why coexistence could persist here even as imperial ideologies hardened elsewhere.
Inside the trenches: walls, floors and the slow reveal of a sacred landscape
The case for early coexistence at Gird‑î Kazhaw rests not on a single spectacular artifact but on the cumulative weight of careful excavation. Archaeologists opened multiple areas on the mound and gradually uncovered brick walls, rammed earth floors and later stone features that together map out a complex of buildings. In one area, the team identified the church‑like hall, while in others they traced domestic structures and installations that likely supported both everyday life and ritual activity. The sequence of construction and modification shows how the settlement evolved, with new walls cutting across older ones and floors resurfaced as needs changed.
Reports on the excavation describe how the team, working layer by layer, brought to the surface in Area A a set of walls and floors that could be tied to distinct phases of use, including the Christian hall and later additions. The discovery of further stone elements in the same zone has opened the door to more detailed interpretations of how the complex functioned and how different religious groups may have moved through it. Coverage of the excavation areas and architectural findings notes that these discoveries will guide further research in coming years, as archaeologists refine the chronology and test how far the pattern of shared space extends across the site.
Reframing religious “tolerance” in late antique Mesopotamia
The finds at Gird‑î Kazhaw invite a more nuanced vocabulary than the simple label of tolerance. What emerges from the trenches is not a modern ideal of pluralism but a pragmatic coexistence shaped by local needs, kinship ties and the rhythms of agricultural life. Christians and Zoroastrians in this village appear to have maintained distinct ritual spaces and identities while accepting that their neighbors worshipped differently, a pattern that fits neither the image of constant persecution nor that of seamless harmony. The later presence of Muslims in the same landscape adds another layer, suggesting that the community adapted yet again as new religious currents arrived.
For historians of religion, this matters because it grounds debates about doctrine and law in the material realities of a specific place. The overlapping Christian, Zoroastrian and Islamic traces at Gird‑î Kazhaw show that religious change in northern Iraq could be incremental and negotiated, rather than dictated solely from imperial centers. I see in this site a reminder that concepts like tolerance, coexistence and conflict are best understood not as abstract categories but as lived arrangements that left their imprint in bricks, floors and reused buildings. The evidence from this one village does not erase accounts of violence elsewhere, yet it complicates any attempt to reduce late antique Mesopotamia to a single story of interfaith relations.
From ancient village to modern debates about shared space
The implications of Gird‑î Kazhaw reach beyond the Sasanian period into current conversations about how different faiths inhabit the same cities and neighborhoods. The site shows that long before modern nation‑states and legal frameworks, communities in northern Iraq were already working out practical ways to share sacred landscapes. Christians, Zoroastrians and later Muslims at this village appear to have navigated overlapping claims without always resorting to exclusion, a pattern that resonates with contemporary efforts to manage multi‑faith urban spaces from Mosul to London. The archaeological record gives those debates a deeper historical horizon, suggesting that coexistence is not a recent experiment but a recurring feature of life in this region.
At the same time, the excavation underscores how fragile such arrangements can be, dependent on local balances of power, economic interdependence and the willingness of neighbors to accept difference. I find it striking that a rural community, far from imperial capitals, left some of the clearest evidence for early interreligious accommodation in Iraq. As scholars continue to analyze the finds from Gird‑î Kazhaw, the site will likely become a reference point not only for specialists in late antiquity but also for anyone interested in how ordinary people, across time, have learned to live with religious diversity under the same stretch of sky.
