A grandiose six-minaret mosque capable of holding more than 60,000 worshippers opened its doors Thursday in Istanbul after nearly six years of construction. Dozens of citizens, along with senior officials from the ruling Justice and Development (AK) Party, joined the morning prayers around 6:30 am (0330 GMT). 'It is a great work of art. I would like to thank our president for making such a project possible in Istanbul,' AK Party mayoral candidate for Istanbul Binali Yıldırım said in statement while cited by Turkey's state-run news agency Sitting atop a hill for which it is named on Istanbul's Asian side, the Çamlıca Mosque complex is one of the mega project of AK Party government. The mosque, which bears traits of Ottoman architecture, is the largest ever built in Turkey, according to the association that funded it. 'It has a capacity of as many as 63,000 worshippers. A conference hall, a library, a museum and a car park for 3,500 vehicles, will serve along with it,' Ergin Külünk, the head of the association of donors that helped finance the project, told dpa. The mosque features several references to Turkish history besides Ottomans. Four of its minarets are 107.1 metres tall, a reference to the 1071 battle between the Seljuk Empire and Byzantine Empire in Manzikert in the south-eastern province of Muş.
