New Gladiator Arena in Austria

[Medusa Gladiatrix]

I got some links for you on this interesting topic, the first one being in English (the most detailed I came across so far):

http://www.pasthorizonspr.com/index.php/...-carnuntum

http://www.spiegel.de/wissenschaft/mensc...60,00.html

http://derstandard.at/1315005480799/Die-...-Carnuntum

Nonetheless the two articles in German have many photos and reconstruction drawings so they are worthwile checking out even if you don't speak German.
