I found the coolest place recently. If you’ve got an extra 10-15 minutes next time you are at the El Paso airport, head to the back of the La Placita shopping area downstairs. It’s to your left before you go up the escalator to the gates.
You’ve got to go all the way back, can’t just poke your head into the La Placita to find this hidden treasure. Heck, this little display of airport history isn’t even on the airport’s own map.
But once you get back there you will find a room with old architectural renderings, models, and other hanging artifacts. Then just to the side of that is display with historical photos, plaques, and other items.
Last but not least, take a look at the wonderful painted ceiling. It shows some of the history of El Paso and Mexico.
