Hagia Sion, Byzantine church building on Mount Zion, Jerusalem, Israel.
Hagia Sion was a five-aisled basilica on Mount Zion, featuring the architectural style typical of Byzantine churches from the 5th century. The building had multiple parallel sections divided by columns, creating a grand interior space for worship.
Construction of the church began in 415 after the discovery of remains believed to belong to Archmartyr Stephen, commissioned by Bishop John II. The discovery transformed the location into an important religious site for Jerusalem's Christian community.
The church served as a pilgrimage destination in medieval times, drawing visitors who came to honor early Christian figures and their remains. People experienced the faith and devotion of the earliest Christian communities through their visit to this holy site.
The remains of this ancient building lie beneath modern religious structures still standing on Mount Zion today. The site is somewhat hidden among other buildings, so it helps to plan your visit in advance if you want to see it while exploring Jerusalem.
The building is documented in ancient maps, including a historic mosaic that recorded its exact location and importance in early Jerusalem. These early map depictions show how people in the ancient world understood and marked this holy place among the city's other landmarks.
