The Blue Mosque is one of Istanbul's most visited sights. It's easy to see why: great location and massive structure. And the mosque is stunning. Formally known as Sultan Ahmed Mosque, it gained the nickname Blue Mosque for the more than 20,000 blue tiles used in the interior. The mosque opened for prayers in 1616.
Approaching the mosque. You can't see them all in this photograph, but one of the unique features of the Blue Mosque is its minarets. There are six of them, more than most mosque designs feature.
The front courtyard. The amazing ceiling.
No doubt, the ceiling draws the eyes of the tourists.
The main prayer area and one more gaze up at that great ceiling. There's one main dome and eight secondary domes. Terrific.
