The Blue Mosque and The Hagia Sophia
The mosque is known as the Blue Mosque because of blue tiles surrounding the walls of interior. The mosque was built between 1609 and 1616 years, during the rule of Ahmed I.
The mosque is covered with rugs as a general tradition in any mosque, so entering the mosque everyone is required to remove their shoes, as they want to keep the carpets clean. Upon entering the mosque and working our way through the crowds the carpet might be clean but the air was well permeated with the odor of thousands of feet.
This is the only mosque in Istanbul having 6 minarets or towers. Muslims are called to prayer from the balconies on the minarets five times a day by the Muezzin.
The interior of the mosque is lined with more than 20,000 handmade İznik style ceramic tiles, in more than fifty different tulip designs.
According Wikipedia, Pope Benedict XVI visited the Sultan Ahmed Mosque on 30 November 2006 during his visit to Turkey. It marks as only the second papal visit in history to a Muslim place of worship.
It’s free to enter the mosque but you do have to stay to the side. They ask for donations on the way out, we gave them a few TL.
