Yes, another day spent looking at mosques. This is the Little Hagia Sophia, which was also built around the same time as its larger cousin. As the name implies, this one is much smaller.

The interior of the Little Hagia Sophia is as intimate as the larger Hagia Sophia's is vast.

This worker is taking advantage of fact that there is always a nice breeze under the arcades around the mosques.

The Book Bazaar is located in the shadow of another enormous mosque, the Beyazit.

Cool shade is also provided by the walls surrounding the mosque courtyards.

The Beyazit Mosque was one of the first grand mosques to be built by the sultans. It is far more ornate on the interior than anything that Sinan produced.

Another Sinan design, the Sehzade Mosque was the architect's first major mosque in the city.

The Sehzade Mosque must have been well used, as the worn marble threshold makes clear.

The fountains in the mosque courtyards are still actively used, and seem to be important meeting places.

The interior of the Sehzade is evocative of Sinan's later grand mosques to come. I was sitting in the back when prayers began, and stayed there inconspicuously throughout the ceremony. It was a powerful experience to see and hear the mosque in action.

Every surface in the mosque resonated with the sounds of the imam's melodious prayers.

The Aqueduct of Valens is an old Roman artifact that now serves as a huge traffic obstruction.

I made a trek to see this mosque, which was built as an ancient church, only to discover that it is closed for renovations.

Istanbul is composed of layers of history built on top, or crammed next to each other.

I made a twenty minute walk out of my way to visit the Fatih Mosque, only to discover, once again, that it is currently being renovated. The tiny glimpses that I got looked impressive, though.

From a distance, it's pretty hard to tell that the Fatih Mosque is being renovated. This does not help those who see it in the distance, and are intrigued enough to make their way to see it (I'm speaking from experience).

Corn on the cob is a popular street snack. The setting's not so bad, either.

These bobbing boats serve what has become my new favorite street food, the local fish sandwiches. Throw in a backdrop of the Suleymaniye on the hill, and I can't resist.

Although I try to sample as much of the food as I can, I've become addicted to these sandwiches, known as "balik ekmek," or "fish and bread." I could not resist getting one for dinner.

Lemon juice and salt are provided on the tiny tables. Nothing else is needed.

I'm not the only one addicted to these sandwiches. The tables were crammed with locals.

I can't imagine that it's easy to cook in these boats, but I guess the guys have had enough practice.

I couldn't resist snapping another photo of the New Mosque, which isn't so new (it was built in the 17th Century).

The New Mosque's arcade has some blue tile work that is vaguely reminiscent of the Timurid tile work that I encountered in Uzbekistan.

The mosque is in an extremely busy district, but the courtyard was surprisingly peaceful.

The Galata Bridge seems to be the most popular fishing spot. It's funny to see these people with enormous fishing poles pulling up sardines.

Istanbul has a huge population of ferrel cats. I sometimes hear them serenading me at night.

This guy sold me a kilo of tasty cherries for $2.

The quay in Eminomu becomes an open air market at night.
