premise: The Kapale Martak (Covered Market) of Istanbul is the world's largest covered bazaar, with about 4,000 shops, as well as banks, cafe, restaurants, mosques, and a post office, crammed together in a grid of 66 narrow streets that total 8 km (5 miles) in length all protected from summer sun and winter rain by a multitude of domed and vaulted roofs.
hypothesis: The Kapale Martak is a small open-air bazaar tucked into an out-of-the-way Istanbul alley.
