They shot on another temple set. It's very Egpytian with large columns around a type of fire pit in the middle and torches on the wall. There's a tapestry on the wall with Egyptian figures on it. At the very top of it, some figures are kneeling to a sun with an eye in it and the sun's rays have hands on them. Next to the tapestry is a spinning wheel (maybe the donkey wheel's cousin?).
I couldn't stick around for shooting but I know I saw Terry O'Quinn (Locke), Michael Emerson (Ben), and some scruffy guy I didn't recognize in the distance.
There were some bloody clothes and a knife and a some fire extinguishers being used in the area, so I guess that means something was going to go down.
