This is a variety of large tent often used to shelter summer events such as shows, festivals, and weddings.
A pole marquee consists of a roof canopy supported by tall central poles (“king poles”) tensioned using side lines connected to ground pins (or stakes) and smaller supporting poles (“side poles”). The king poles support the bulk of the weight, while the side poles give the fabric shape.
Originally, they were manufactured from cotton canvas covers, wooden poles, and hessian rope but they have been largely replaced with PVC covers, aluminium poles, and nylon ropes. The introduction of modern fabrics extends the shelf life of the marquees, as they are far more easily cleaned.
