The freeways connecting Al Ain, Abu Dhabi, and Dubai form a geographic triangle in the country, each city being roughly 130 kilometres (81 mi) from the others.'City of The Garden')[1] of Abu Dhabi,[3] the UAE[4] or the Gulf,[5][6] due to its greenery, particularly with regard to the city's oases,[2] parks, tree-lined avenues and decorative roundabouts, with strict height controls on new buildings, to no more than seven floors.Oman lies to the east, Dubai and Sharjah to the north, Abu Dhabi to the west and the Empty Quarter desert and Saudi Arabia to the south.[20][21] Sand dunes of varying texture that are tinged red with iron oxide lie to the north and east of Al Ain.[citation needed] To the south of the city, near Oman, there is the man-made Lake Zakher, which resulted from the release of waste water from desalination plants.One such souq exists for camels near an IKEA store and Bawadi Mall on Zayed Bin Sultan Street,[2] the road which leads to Mezyad.[6] Industry is growing on a small scale, and includes the Coca-Cola bottling plant and the Al Ain Portland Cement Works.[32] For example, the area witnessed events relevant to the history of Islam during the Rashidun, Umayyad and Abbasid eras, similar to Dibba and Ras Al-Khaimah.[38][39] Part of the historically important Western Hajar region,[40][41] the area of Al Ain has been inhabited for nearly 8,000 years, with archaeological sites showing human settlement at places like Rumailah, Hili and Jabel Ḥafeet.For instance, the Wadi Suq communal tomb at Qattara Oasis is thought to have been constructed from stones recovered from previous Umm Al Nar burials.[44]Finds at Qattara include Wadi Suq era chlorite jugs and bowls and late Bronze Age short swords and daggers.A find of particular interest from Qattara is a Bronze Age pendant discovered in the 1970s depicting a double-bodied or entwined pair of horned animals.[45] Made from electrum, an alloy of silver and gold, the motif is found repeated in a number of Bronze Age sites in the UAE.[46] Al Ain was originally within the area of influence of the Dhawahir, a Bedouin tribe who settled Dhahirah before Buraimi.[47] Numbering 4,500, the Dhawahir consists of three subsections: the Daramikah, who populated Hili, Mutared and Qattara; the Jawabir in Al Ain and the Bani Saad who lived in Jimi.With British intervention, the Saudi forces surrendered, leaving the oasis back in the hands of Abu Dhabi and Oman.Following independence in 1971, Al Ain experienced rapid growth and investment as part of the emirate of Abu Dhabi,[49] quickly becoming larger and more successful than Oman's Al-Buraimi.Falaj irrigation is an ancient system dating back thousands of years, and is used widely in Oman, the UAE, China, Iran and other countries.Al-Ain is also the home of Horizon International flight academy, Etihad Airways's cadet pilot training centre.[60] Al-Khwarizmi International College has started a Campus at Al-Ain and is offering BBA programme and various other licensed, accredited and approved courses.Opened in 2012, Al Ain Adventure park is located near Jebel Hafeet and provides a range of water-based activities including surfing, kayaking and rafting.[78] Al-Ain Club contains also eight other games which are: handball, volleyball, basketball, swimming, Table Tennis, Athletics, Jiu jitsu, and Taekwondo.
