Temenos Gateway sits proudly across the colonnaded street, marking its western edge. It's also hiding the fact that the Colonnaded Walk veers slightly to the right if looking from the Great Temple. But it was also the entrance to the most important sacred precinct (the temenos) in Petra - that of Qasr el-Bint Faroun.
The gate is built in the style of a triumphal arch, and was not compeleted until after the Colonnaded Walk has been completed. It is undergoing serious reconstruction - little of the original remains. The old heart of Petra was the most exposed to the elements.
Nowadays, it is also the demarkation for the more modern day concept of te market. Just beyond the Gate is a place teeming with activity - you will find 3-4 cafes/restaurants, the small but rather interesting hillside museum, many donkeys waiting to take you up to the Monastery, a few hawkers as well as, due to the first sign of shade, a place to hang out.
At one of the ends of the "main street" you can see the remains of the Temenos Gate. Originally it had three archs, and were the main entrance to the sacred place, the temenos. The majestic gate was built after the main street pavement was finished, and some of the stones had to be removed from the floor.
The Temenos Gate was probably the entrance to the Qsar Al-Blint Temple. The gateway is decorated with very well preserved stone carved flowers and animal designs that were popular with the Nabataeans. There are also border columns that cannot be seen on this photograph (they are on the other side of the ruins) that are an example of how the Romans and Nabataeans merged their respective architectural styles during the period of Roman domination.
At the end of Cardo Maximus there is the Temenos Gateway. It was build in the second century AD and it had got three arches, towers and doors made by wood but noe it's very difficult to imagine how it was when it was build. In the background the mountain seems a camel ;)
