What is an altar rail?
An altar rail (also called a communion rail) is a low railing or barrier in a church that separates the chancel or choir area from the nave, marking the boundary between the clergy’s space and the congregation. Worshippers traditionally kneel at the altar rail to receive communion.
Purpose and function
The altar rail serves several roles in church architecture:
- Liturgical boundary — it physically marks the transition from the public nave to the sacred sanctuary
- Communion station — congregants kneel along the rail to receive bread and wine during the Eucharist
- Symbolic threshold — it represents the separation between the earthly (nave) and the divine (altar)
- Practical barrier — it prevents unrestricted access to the altar and its sacred vessels
History
| Period | Development |
|---|---|
| Early Christian | No physical separation; the altar stood freely among the congregation |
| Medieval | Rood screens (large carved wooden or stone screens) separated chancel from nave |
| Post-Reformation (16th-17th c.) | Rood screens were often removed; simpler altar rails were introduced |
| 17th-18th century | Altar rails became standard in Anglican and Catholic churches |
| 20th century onward | Many churches removed or opened rails to encourage congregational participation |
Construction and materials
Altar rails are typically built from:
- Wood — oak, walnut or other hardwoods, turned or carved with decorative spindles or balusters
- Wrought iron — ornamental metalwork, often with scrolls and floral motifs
- Stone or marble — in grander churches and cathedrals, sometimes with carved panels
- Brass or bronze — polished metal rails, common in Victorian-era churches
Typical components
- Top rail — a smooth, flat or rounded horizontal rail for resting hands
- Balusters or spindles — vertical supports between the top rail and the base
- Kneeling step — a padded or wooden step at the base where communicants kneel
- Gate or opening — a central gap or hinged gate allowing the clergy to pass through
Dimensions
Common dimensions for an altar rail:
- Height: 80-100 cm from the floor
- Length: spans the full width of the chancel opening, typically 3-8 metres
- Baluster spacing: 10-15 cm apart
Restoration and preservation
In historic churches, altar rails are often protected as heritage elements. Restoration work may involve:
- Repairing or replacing damaged balusters while matching the original profile
- Stripping and refinishing woodwork
- Repointing stone bases
- Replacing worn kneeling pads
