Sarajevo was once the second most important Ottoman city, a huge metropolis and site of the largest Islamic library in the world. On this side of town, legends of the Orient still swirl in the alleys.
There's a big architectural difference, but the two sides of Old Sarajevo still feel like the same city. It's a fairly homogenous capital, and almost everyone, everywhere, is Muslim and Bosniak. The culture doesn't change from place to place, only the sense of history.
