Before the rise of the Ottoman Empire, most of Turkey was divided into small kingdoms, or beyliks. The İsa Bey Mosque was completed in 1375 and is considered one of the most important buildings of the era. The fortresslike exterior is arguably more impressive than its interior which, like many mosques, is understated and spare in decoration. Male visitors who want to enter the mosque should wear long pants, and women should come with a shawl to cover their head.
