It's well known it was never an actual treasury; there's not much inside to it, and it's the first main "building" you see when entering through the canyon, designed to impress rather than store valuables. The name comes from rumour/legend: https://en.wikipedia.org/wiki/Al-Khazneh#Name https://en.wikipedia.org/wiki/Al-Khazneh#Name. Most of the cliff structures are tombs.
