A circus is a traveling entertainment show that features a variety of performances, including acrobatics, clowns, and animal acts. It typically takes place in a large tent called a big top and showcases skilled performers who entertain audiences with their talents. Circuses have a long history, dating back to ancient times, and have evolved over the years. Today, many circuses focus on human performances, emphasizing artistry and athleticism, while some still include trained animals. Popular circuses, like Cirque du Soleil, have gained international fame for their unique and creative shows.
