Ed-Deir, Petra

Ed-Deir (Arabic: الدير, lit. 'The Monastery'), also spelled el-Deir and ad-Deir/ad-Dayr, is a monumental building carved out of rock in the ancient city of Petra in southern Jordan. The Deir was probably carved in the mid-first century AD. Arguably one of the most iconic ancient Arab monuments in the Petra Archaeological Park, the monastery is located high in the hills northwest of the Petra city center. It is the second most commonly visited monument in Petra, after the Khazneh or "Treasury".

The huge façade, the inner chamber and the other structures next to it or in the wider area around the Deir probably originally served a complex religious purpose, and was possibly repurposed as a church in the Byzantine period.
