# What is a berceau?
**A berceau is an arched garden structure — a pergola or arbour with a curved, tunnel-like framework — that is covered with trained climbing plants to form a continuous green canopy overhead.** The word comes from the French “berceau,” meaning cradle, referring to the rounded, cradle-like shape of the overhead arch. Berceaux have been a feature of formal European garden design since the Renaissance.
## How is a berceau constructed?
A berceau consists of two main elements:
### The framework
– Traditionally built from bent wooden laths, wrought iron or steel hoops
– The arches are set at regular intervals (typically 1-2 metres apart) along a garden path
– Horizontal rails or wires connect the arches to support the climbing plants
– The structure must be strong enough to bear the weight of mature vegetation, which can be considerable
### The planting
– Climbing plants are planted at the base of each upright and trained over the framework
– Common species include hornbeam, lime (linden), wisteria, climbing roses and grapevines
– Regular pruning and tying-in are essential to maintain the tunnel shape
– A mature berceau can take 5-10 years to fully establish
## Application
Berceaux are found in:
– **Formal gardens and estates** — as shaded walkways connecting garden rooms or leading to focal points
– **Palace gardens** — Versailles and many other historic European gardens feature elaborate berceaux
– **Public parks** — providing shaded promenades and visual interest
– **Modern garden design** — scaled-down versions used in residential gardens as decorative covered paths
### Design considerations
– Orient the berceau to frame a view or create a sense of progression toward a destination
– The interior height should allow comfortable passage, typically 2.2-2.5 metres at the crown
– Width is usually 1.5-2.5 metres for a single walkway
– Ensure adequate drainage at the base and access for maintenance
