Monastery (Ad Deir)

Ad Deir — Arabic for 'the Monastery' — is a Nabataean rock-cut monument carved directly into the rose-red sandstone cliffs above ancient Petra during the 1st century CE. At 50 metres wide and roughly 39 metres tall, it actually surpasses the more famous Treasury (Al-Khazneh) in sheer scale. The 'monastery' name comes from Byzantine-era crosses scratched into the interior walls by later monks; the structure itself was likely a royal tomb or cultic monument dedicated to the deified Nabataean king Obodas I. Reaching it requires a 45–60 minute climb up approximately 800 rock-cut steps through a winding gorge. The reward at the top is a near-deserted plateau with an unobstructed view of the monument's facade and sweeping panoramas across the Jordanian desert — best experienced in the late afternoon light.
