The Monastery, or Ad Deir, is an awe-inspiring ancient structure carved out of the rose-red sandstone in the archaeological city of Petra, Jordan. Believed to be established as a Nabatean tomb around the 1st century AD, it was later used as a Christian monastery, which is where it gets its name. The facade of the Monastery is grand, measuring 47 meters wide and 48.3 meters high. It is accessible today by a steep climb of approximately 800 rock-cut steps that wind through the mountainous terrain, offering breathtaking views along the way. The Monastery's remote location and the arduous trek required to reach it make the site less crowded, offering a more peaceful experience compared to the Treasury (Al-Khazneh), another famous landmark in Petra. Its Hellenistic architectural details are similar to that of the Treasury, but because of its size and high elevation, the Monastery boasts a uniquely majestic presence with stunning views over the surrounding mountains and valleys. Ad Deir is not just a testament to the architectural prowess of the Nabateans but also a cultural melting pot reflecting the multiple civilizations that once flourished in this region.
