A plaza on Xandar serves as the introduction of Gamora, Rocket and Groot as they try to steal the Orb from Peter Quill.
The Liége Guillemins Railway Station, in Belgium, served as the model for the Xandarian plaza, where the team was arrested and taken to the Kyln. The actual plaza scenes were filmed on a studio set at Longcross Studios according to Cinefex #139.
