That mosque which dominates the skyline of the city, built on a slightly higher hill than its surroundings, although a play on dimensions makes the exterior sight of the building smaller as you get closer to it. A grandiose piece of art by Mimar Sinan, the Ottoman architect of 16th century, Selimiye is usually considered the zenith of Ottoman architecture and has been listed as a World Heritage site by UNESCO in 2011. Sinan himself considered this building as his best work. The dome of the building, which hangs high over main hall, encloses a huge space which gives the place an expansive atmosphere, had the largest diameter (31.28 mt) of all domes in the world for several centuries. And its minarets (towers) are the second highest minarets (70.89 mt) in whole world, surpassed only by Qutb Minar (72.50 mt) in Delhi, India. The mosque has 999 windows in total, which according to its architect Sinan, symbolize the perfectness of God, through the imperfectness of the mosque he designed. The dome and interior walls are decorated with calligraphy and geometrical designs, most of which are painted in hues of pink and blue. If you have admired Blue Mosque (Sultanahmet Mosque) of Istanbul, you’ll sure adore this one, since Blue Mosque is quite a copy of Selimiye. The upside down tulips, which are some sort of symbol of Edirne have their origin in a tulip illustration engraved on a marble in the fountain right under the central dome of Selimiye. It is believed to symbolize the landlord of the tulip garden on which the mosque was built, who was said to be reluctant to give over his garden.
