Here are some pictures of the exterior of the mosque. The first photograph is the approach to the mosque.
The six minarets of the mosque are visible. When the Blue Mosque was built, it was the only mosque in Turkey with six minarets (now there is one at Adana too). At the time even the mosque of the Ka'aba at Mecca did not have six minarets and the Sultan was criticized for building a mosque with more minarets than the one at Mecca. He tackled this criticism by getting a seventh minaret built at the Mecca mosque.
This is the entrance to the mosque.

Another picture of the Blue Mosque.
It was raining continuously when we visited the Blue Mosque. I thought that the bobbing umbrellas against the backdrop of the mosque looked pretty.
