The clown alley in a circus is a backstage area, usually very near the animal pens, where clowns change into their costumes and apply makeup.
Generally, the clowns' personal props, costumes, and other items are stored in this area as well.
If the circus show had some problem with a performance, the ringmaster could yell out "Clowns Allez" meaning “Clowns Go!” Today, most clowns do not use tents for dressing and make up, as travel trailers or motor homes are used.
The term has also come to mean any professional grouping of clowns, in general, regardless of whether or not they are affiliated with a circus or carnival.
A Clown Alley Local will co-ordinate social events as well as professional development for members, as well as direct employment opportunities.
