The Djerba amphitheatre

Location
Djerba, Tunisia
Building
Amphitheatre
Structure
Membrane roof on a steel truss arch and masts
Scope
Design · Engineering · Installation

A wide span, and not one column in sight.

The textile roof spans the stage and the tiers without intermediate supports: a clear view from every seat and effective protection from the sun.

01The arch

The backbone comes first.

A steel truss arch spans the site. The cables hanging from it already set the geometry the roof will take.

02Installation

On site, turnkey.

Cranes, an aerial work platform, specialist riggers: fabrication, logistics and installation from a single contractor, through to the finished roof.

03The result

A sail over stage and tiers.

By day, luminous shade over the tiers; by night, a glowing roof: the membrane holds the light that passes through it.
