By choosing the central city of Isfahan, with the Zāyande roud ("The life-giving river"), lying as an oasis of intense cultivation in the midst of a vast area of arid landscape, he distanced his capital from any future assaults by the Ottomans, the arch rival of the Safavids,[4] and the Uzbeks, and at the same time gained more control over the Persian Gulf, which had recently become an important trading route for the Dutch and British East India Companies.
[5] The chief architect of this colossal task of urban planning was Shaykh Bahai (Baha' ad-Din al-`Amili),[6] who focused the programme on two key features of Shah Abbas's master plan: the Chahar Bagh avenue, flanked at either side by all the prominent institutions of the city, such as the residences of all foreign dignitaries, and the Naqsh-e Jahan Square ("Exemplar of the World").
Abbas wanted to undermine this political structure, and the recreation of Isfahan, as a Grand capital of Iran, was an important step in centralizing the power.
For the hungry, there were readily available cooked foods or slices of melon, while cups of water were handed out for free by water-carriers paid for by the shop-keepers.
At dusk, the shop-keepers packed up, and the huzz and buzz of tradesmen and eager shoppers bargaining over the prices of goods would be given over to dervishes, mummers, jugglers, puppet-players, acrobats and prostitutes.
Also, the national Persian sport of polo could be played in the maidan, providing the Shah, residing in the Ali Qapu palace, and the busy shoppers with some entertainment.
[11][12] Under Abbas, Isfahan became a very cosmopolitan city, with a resident population of Turks, Georgians, Armenians, Indians, Chinese and a growing number of Europeans.
[16] The Crown Jewel in the Naqsh-e Jahan Square was the Masjed-e Shah, which would replace the much older Jameh Mosque in conducting the Friday prayers.
[18] Ali Qapu (IPA: ɑliː qɑpuː) is a pavilion that marks the entrance to the vast royal residential quarter of Safavid Isfahan which stretched from the Maidan Naqsh-e Jahan to the Chahar Bagh Boulevard.
From the upper galleries, the Safavid ruler watched polo games, maneuvers and horse-racing below in the Naqsh-e Jahan square.
