1st is the rose bridge, 2nd and 3rd are fallas (pronounced fayas) is the falla museum. They are made of wire frames and covered with paper mache. They make a ton of them for a huge celebration in March and burn all of them except the one favorite at the end of the celebration. The last picture is a cologne ad that is very Zoolanderesque.
The top picture is kind of random but we just had to take it. Why are the display models aliens? I definitely gotta get those clothes.
