Mar'na Memorial Stadium was a large public forum in the city of Iaron on planet Damiano. Named for legendary leader Mar'na F'ullhy, it was the largest gathering place in the hemisphere.

The stadium was built by Pad'gy D'ullh, a brutal tyrant who used the stadium for bloody gladiatorial competitions. Mar'na Memorial Stadium remained in use for centuries to follow, though Pad'gy's role in its construction was often left out of the facility's official history.
