In The Last Crusade, Indiana Jones is after the Holy Grail, and what better place to house it than in a real-life place called The Treasury? That's the popular tourist attraction, the Al Khazneh, in Petra, Jordan, a giant, ornately carved sandstone temple facade, which dates back to the first century AD.

Yes, the "Temple of the Sun" featured in Indiana Jones and the Last Crusade is a very real and spectacular archaeological site known as Al-Khazneh (The Treasury), located in Petra, Jordan. Carved directly into the rose-red sandstone cliffs by the Nabataeans in the 1st century BC, the exterior facade seen in the movie is nearly identical to what you can visit today. However, it is important to note that only the exterior was filmed on location. The cavernous, booby-trapped interior shown in the film—where Indy meets the Grail Knight—was a Hollywood set built at Elstree Studios in London. In reality, the space behind the famous facade is a relatively small, plain square chamber that was likely used as a royal tomb or mausoleum. In recent years, including discoveries made in late 2025, archaeologists have even found hidden tombs beneath the Treasury's floor, adding more real-world mystery to the cinematic legend.
