Tollatur ____! Let the stadium be abolished! (it's unsafe, Ovid claims, Tr. 2.283) (6)
I believe the answer is:
circus
(Other definitions for circus that I've seen before include "Performance by acrobats, clowns and animals" , "Ring entertainment" , "Street formed in a circle" , "Group of travelling performers" , "Trvelling company of entertainers, usually with animals" .)
