Final answer:
The Globe Theatre, associated with William Shakespeare, was an open-air, circular theatre with three levels of seating, which can technically be considered as three walls.
Step-by-step explanation:
The Globe Theatre was a historic structure located in London, England. This theatre, famous for being associated with William Shakespeare, was a circular, open-air playhouse that had three stories of seating encircling half the stage, hence representing a 'half-circular' shape. Therefore, technically we can regard it as having three walls if we count each level of seating as a separate 'wall'.
