Bringing new meaning to the idea of juggling or balancing the books, the St. Louis Arches are the high-flying performance troupe from Circus Harmony. The Arches, an acclaimed group of young performers based at City Museum, will perform a variety of circus arts including acrobatic, aerial, juggling and balancing feats of skill and daring. For more than a decade, the Arches partnered with the Jewish/Arab Galilee Circus in Israel, and the children’s book Watch Out for Flying Kids captures the spirit of this partnership.
