Among the ancient civilizations of Europe and the Middle East, such as the Egyptians, the Mycenaeans, and the Assyrians, it is the Hittites that seem to hold to their reputation of the mysterious people with a largely unknown history. During the period of their greatest might, in the second half of the 2nd millennium BCE, they were perceived as equals by the Egyptian and the Mesopotamian superpowers. This guidebook, The Secrets of Hattusa, takes the readers on the tour of the Hittite capital city. We begin the adventure with the brief introduction of the Hittite civilization, its main achievements, religion, and the form of government. Throughout the guidebook, you will find numerous photographs of the discussed locations and artefacts. Their goal is to serve as visual clues for visitors who want to understand clearly what they can see in Hattusa, Yazılıkaya, and Alacahöyük. There are also photos from other locations, such as the museums in Ankara, Berlin, and Istanbul, where many finds from these sites are on display. Last but not least, a detailed plan of the Hattusa archaeological site is included in the book, with the points of interest clearly marked. If, after reading this guidebook and the visit to Hattusa you decide to learn more about the Hittites, the final section contains an extensive bibliography on the subject.
