The Monastery, for example, was a temple which also featured a great dining room. There is also the Theatre, which, as its name suggests, is a theatre built after the Hellenistic fashion. There are also spaces that have been identified as markets, and an audience hall found in the Great Temple.

The Ad Deir, or "The Monastery," is one of the most imposing and famous monuments in the ancient Nabataean city of Petra, Jordan. Much like the more famous Treasury (Al-Khazneh), the interior of the Monastery is surprisingly simple and sparse compared to its grand, ornate exterior facade. Inside, there is a single, large, square chamber carved directly into the yellow sandstone. The walls are plain and unfinished, lacking the intricate carvings or inscriptions found on the outside. At the back of the chamber, there is a recessed niche or "dais" carved into the wall, which archeologists believe may have originally housed a sacred stone block or a statue representing a Nabataean deity. The name "Monastery" comes from the fact that crosses were carved into the interior walls during the Byzantine period when the structure was repurposed as a Christian church or place of worship. There are no hidden tunnels, gold, or ancient treasures inside; the true value of the site lies in its massive architectural scale and the breathtaking views of the surrounding Wadi Araba desert from the plateau outside.
