By the 1st century BCE, Petra was flourishing as the Nabataean capital. Unlike many ancient cities, Petra wasn’t built on the rock, it was built from it.
The Nabataeans carved their temples, tombs and monuments directly into the sandstone cliffs, creating façades that seem to glow at sunrise.
Their architecture reflected a blend of influences: Hellenistic design (particularly the ornate Corinthian columns of The Treasury), Arabian artistic traditions and local desert engineering.
Petra also developed into a cosmopolitan city with markets, water channels, cultivated gardens and complex streets.
Diplomacy played a role too. Unlike some desert kingdoms, the Nabataeans rarely sought open conflict.
Instead, they negotiated favourable relationships with neighbours, levied tolls on caravan traffic and maintained autonomy during the Hellenistic period and early Roman expansion.
