Oasis of the Pillars (Great Empires)

Oasis of the Pillars (Arabic: احة أركان) also known as City of Canals(Arabic: مدينة القنوات) and Medina al-Kanuat was once the most exotic and mythical city on Earth. Located in the middle of the Arabian Desert, the city was considered a myth and legend in most parts of Europe and Asia. Few knew of it until Ibn Battuta made it known in most of the civilized world in 1366.

History
Before its founding there was nothing at the place except for a small oasis. It was founded in 786 when Khayzuran bint Atta, calipha of the empire began construction of a city that the world had never seen before and as her holiday residence. More than a million construction workers began building canals, aquaduct, houses and the Adzihar-Qasara  (Floating Palace). Her personal advisors and architects designed a special system of aquaducts that carried water from the Eastern Arabian Aquifer and other sources of water to the city. In just 20 years of time the city grew from zero to more than 100,000 inhabitants. The city became one of the most habitable and pleasent cities of the world. But it's location kept the city hidden for hundreds of years, only appearing in legends and tales in Europe and Asia. Only a few people have visited the city before 1366 and those who did never returned because they would stay in the city forever.
