Geonosis Arena
From Lego Star Wars Wiki
The Geonosis Arena was an arena used for executions on Geonosis. Its actual name is the Petranaki Arena. In Episode II, the executions of Anakin Skywalker, Padmé Amidala, and Obi-Wan Kenobi used an Acklay, a Reek, and a Nexu. In the Lego® version, they were going to be executed by a droid firing squad.
