Manisa is a historic town in Western Anatolia beneath the north side of Mount Sipylus that became part of the Ottoman Empire in the 15th century. During Ottoman rule the town was governed by several princes (called Şehzade) and so is also known as a town of the princes (Şehzadeler şehri). Many examples of Ottoman architecture were built over the next few centuries, such as the Muradiye Mosque, designed by the famous architect Mimar Sinan in 1586, and built for Murad III who was a governor of the town.
