Finally we reached the top plateau where Al-Dayr resides. It is one of the largest monuments in Petra, measuring 47m wide by 48.3m high. It was built on the model of the Khazan but here the bas-reliefs are replaced by niches to house sculptures. A columned portico extends in front of the facade. The interior is occupied by two side benches and an alter against the rear wall. It was used as a biclinium for the meetings of religious associations, and dates to the early 2nd century AD, during the reign of King Rabel II. In Byzantine times the hall was repurposed as a Christian chapel and crosses were carved in the rear wall which was when it took on the appellation "Monastery" (Dayr in Arabic).
After spending some time recovering from the climb up, appreciating the grandeur of the Monastery itself, and doing some people watching, there was the long walk back down all those stairs.
