Some photos have been posted online at Tumblr, which presumably show Peacekeepers in District 11 for The Hunger Games: Catching Fire. While the actual location of this set is unknown, the setting resembles the given description of District 11 strongly, as noted by HGT.net.
Check out the photos in the gallery here.
Apart from these photos, close-up shots of the Justice Building are also available thanks to Instagram users Cobradoll, Bonheath and ErinP87. The building is still standing, and they might use it for later filming / alternate scenes.

So I was at dinner for homecoming tonight, and I look over and saw the actor who was cast as Peeta’s brother for Catching Fire LITERALLY RIGHT NEXT TO US and we went over and talked to him and he’s a super cool guy and we tweeted him. He favorited and retweeted all of us, then tweeted us back, me twice. And it was just super cool and I freaked out a bit.
