As you reach the top of the mountain you will come to what is known as Attuf Ridge. On this ridge are two obelisks, such as are found in India.
Most certainly they came from the Attuf Ridge where the Nabataeans carved away the

Petra's theater is cut out of solid rock, and badly deteriorated. The front of the theater, including most of the stage was badly damaged by floods.
While some people have assumed that this was built by the Romans, the theater is actually Nabataean and was constructed long before the Romans entered Petra.

It had two layers of vaults and is thought to be the tomb of the Nabatean king, Malchus II. It was converted into a church by the Byzantines. They flattened the floor of the tomb and put in an altar
The Urn Tomb is a well-preserved monument facing an open terrace fronted by a double row of vaults. A colonnaded cloister runs along the northern side of the terrace. Behind the facade is a single, unadorned room measuring 60 feet on each side..

Petra "petra-πέτρα", cleft in the rock in Greek; Arabic: البتراء, Al-Batrāʾ) is an archaeological site in the Arabah, Ma'an Governorate, Jordan, lying on the slope of Mount Hor in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. It is renowned for its rock-cut architecture. Petra is also one of the new wonders of the world. The Nabateans constructed it as their capital city around 100 BCE.
The site remained unknown to the Western world until 1812, when it was introduced to the West by Swiss explorer Johann Ludwig Burckhardt. It was famously described as "a rose-red city half as old as time" in a Newdigate prize-winning sonnet by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage." In 1985, Petra was designated a World Heritage Site.
By bus
JETT buses, both ordinary and all-inclusive guided tour, connect to Amman and Aqaba. Other tourists come with organized groups, including daily trips from Eilatm. Tours to Petra from Taba, Sinai and Sharm el Sheikh are also gaining popularity with charter tourism.
By minibus
The minibus from Wadi Rum costs 3 Jordanian Dinars (JD) each. It takes 1.5 hours to get to Petra. Have the Rum Guesthouse or your tour operator call the bus owner the day before to arrange an exact time for pick up. The bus usually leaves from Wadi Rum at 8:30 in the morning, but may be delayed due to weather or tour groups coming the other way.
There are also minibuses from Amman departing from the Wadabat bus station - these leave when full, and tourists are almost always charged 3 JD to get on. DO NOT allow the drivers to charge you for your luggage, as they might sometimes try to do, considering you're already paying more than the locals (who pay 2-2.5JD).
By taxi
Taxi is also a viable option. For 75 JD or less (depending on how much you haggle) you may be able to get a private taxi from Amman to Petra and back, including the driver waiting around for 6 hours. It would cost 24 JD for two persons to travel by JETT bus, and allow you to see almost the entire site in an (exhausting) day trip.
If you get there renting a minibus with a driver in the hotel at the Dead Sea, the one-way price would be 140 JD.

The ruins remained hidden to most of the world until the Swiss explorer, Johann Ludwig Burckhardt, disguised as an Arab scholar, infiltrated the Bedouin-occupied city in 1812. Burckhardt's accounts of his travels inspired other Western explorers and historians to discover the ancient city further. The most famous of these was David Roberts, a Scottish artist who created a number of accurate and detailed illustrations of the city in 1839.
