Wonder place of the world

PETRA YORDANIA

One of the 7 new wonders of the world is Petra. Determination of the seven wonders of the world is the choice of 100 million people around the world via the internet website and text messages (SMS), which are held by the Swiss Foundation, and announced in Lisbon, Portugal, on 07-07-07 or 7 July 2007.

Petra is a city founded by carving stone walls in Jordan. Petra comes from the Greek which means 'stone'. Petra is a symbol of technique and protection.

This word refers to the building of his city made of stones in Wadi Araba, a hollow valley in Jordan. The city was founded by digging and carving rocks as high as 40 meters.

Petra is the capital of the Kingdom of Nabatea. Founded nine years before Christ until the 40th year AD by King Aretas IV as a city that is difficult for the enemy to penetrate and safe from natural disasters such as sandstorms.

The Nabateans built Petra with an extraordinarily complicated irrigation system. There are water tunnels and water chambers that deliver clean water to the city, thus preventing sudden flooding. They also have hydraulic technology to lift water.

There is also a theater that can accommodate 4,000 people. Now, the Hellenistic Graveyard Palace which has a height of 42 meters still stands impressive there.
