I believe the answer is:

arenas

(Other definitions for arenas that I've seen before include "Areas for events, sporting perhaps" , "Places of sports contests" , "rings" , "Central areas of, say, sports stadiums" , "Central spaces of stadiums or amphitheatres" .)

I've seen this clue in The Guardian.
