Archaeologists unearth the aqueduct that once fed the Temple Mount
Construction planning south of Jerusalem uncovered a 300-meter stretch of the ancient Lower Aqueduct of Jerusalem. Archaeologists believe the aqueduct was built during the Hasmonean period, about 2,000 years ago, to bring water from Solomon’s Pools to the Temple Mount. The 21-kilometer channel relied on a carefully engineered gravity-fed slope, with tunnels and access points for maintenance. Water supplied the Second Temple’s ritual purifications and cleaning; the aqueduct was later fitted with Ottoman-era pipes and remained in use intermittently until about a century ago.

Archaeologists have uncovered a 300-meter stretch of Jerusalem’s Lower Aqueduct near Ramat Rachel. The roughly 2,000-year-old channel carried water from south of Bethlehem to the Temple Mount and is expected to be preserved as part of a planned neighborhood. 1
The Israel Antiquities Authority announced the find on October 11 during preparations for a residential development south of Kibbutz Ramat Rachel. Excavation directors said the aqueduct was probably built under the Hasmonean kings, who ruled Judea from about 140 to 37 BC. 1
The aqueduct ran about 21 kilometers (13 miles) from Solomon’s Pools, south of Bethlehem, to the Temple Mount. It relied on gravity, descending by about one meter per kilometer along much of its route. Its stone walls enclosed a plastered, U-shaped channel, likely covered with stone slabs; tunnels were cut through hills where needed to maintain the route’s gradual slope. 1
The system included access points for clearing blockages. During the Ottoman period, ceramic pipes were installed inside the older channel, and the aqueduct remained in intermittent use until roughly a century ago. 1
The aqueduct supplied water for the Second Temple, including ritual purification and cleaning the courts and altars after sacrifices. Religion scholar Douglas Estes said Jesus, his disciples, and early Christians would likely have used the system when visiting Jerusalem for pilgrimage festivals, though no direct archaeological evidence connects particular people to the channel. 1
The article also places the aqueduct in the context of ancient water engineering, noting that it was built around the same period as a Roman aqueduct supplying the Temple of Jupiter in Rome. It connects the Jerusalem water supply with the Sukkot water-pouring ceremony and the Gospel of John’s account of Jesus speaking about thirst and water in the Temple courts. 1
Only about two kilometers of the aqueduct’s full route have been excavated. Researcher Gil Freid has used satellite mapping to trace probable sections farther north. 1
The Israel Antiquities Authority and Israel Land Authority plan to preserve the exposed section and incorporate it into the entrance to a neighborhood expected to include up to 1,800 homes. Proposals also include a park and promenade along the aqueduct toward the Old City; the development has drawn criticism from international organizations concerned about construction between East Jerusalem and Bethlehem. 1
Infrastructure shapes religious ritual and sacred communal life
Infrastructure does not merely house religious practice; it helps shape how a community gathers, moves, listens, sees, and understands itself. In Christian worship, however, the building is not sacred in isolation: its meaning comes from its service to the gathered people and the liturgy they celebrate.
A church’s layout can make communal roles and actions visible. Space for proclamation, song, movement, silence, and the Eucharist supports the different ministries of the assembly; good design enables these actions without reducing the building to a merely functional venue. The architecture can also express that the Church is a people united in Christ, rather than simply a collection of individuals sharing a room.
This relationship is reciprocal. The assembly gives the space its liturgical meaning, while the space helps the assembly gather and act as a community. In that sense, the church building can serve as a “spatial icon” of the Church—but the building is not identical with the Church, which is the people of God.
The same principle applies beyond church buildings. Homes, sanctuaries, streets, and squares can provide settings for prayer or expressions of popular piety, though their uses and significance differ.
So the claim is sound, with an important qualification: infrastructure shapes ritual and communal life, but it does not determine them. Christian sacred space serves the worship and life of the community; it should be worthy of the mystery celebrated there and help carry the fruits of worship into everyday life.
