Looks like a junkyard for neon signs, and that’s exactly what it is! The Vegas Boneyard is a part of The Las Vegas Neon Museum, open to serve as inspiration to fascinated artists, students, historians and designers.

It is home to some of the most treasured and world-famous signs of Las Vegas—Caesars Palace, Binions Horsehoe, Golden Nugget, Silver Slipper, and, most recently the Stardust. The three-acre Neon Boneyard houses more than 150 historic, non-restored signs.
