Deep Memory of the Steppe: Karacahisar Fortress, Halil İnalcık's Legacy, and a New Vision for Eskişehir
What makes Eskişehir's history truly unique on a world scale is Karacahisar Fortress, standing silently on a hill overlooking the Porsuk Valley — the very place where the Ottoman Empire was born.
Deep Memory of the Steppe: Karacahisar Fortress, Halil İnalcık's Legacy, and a New Vision for Eskişehir
When most people hear "Eskişehir," they think of the lively cafés along the Porsuk River, the colorful streets of the historic Odunpazarı houses, or the city's vibrant university atmosphere. Yet beneath its modern identity, this land holds a vast historical layer that has shaped the destiny of civilizations for thousands of years.
But how aware are we of the greatest heritage lying in the heart of this city — one that changed the course of world history?
From Phrygia to Dorylaion: The First Traces of Time
Since the Early Bronze Age, Eskişehir has been a crossroads of trade routes through Şarhöyük (Dorylaion), a center of mystical beliefs in the Phrygian Valley and the City of Midas. In the Roman and Byzantine eras, it served as a supply base where armies gathered strength at its healing thermal springs, and it witnessed fierce battles that changed the course of the Crusades.
But the true turning point that makes Eskişehir's history unique on a "world history" scale is **Karacahisar Fortress**, standing silently on a hill overlooking the Porsuk Valley, southwest of the city.
Where an Empire Was Born: Prof. Dr. Halil İnalcık and Karacahisar
The world-renowned historian **Prof. Dr. Halil İnalcık**, known globally as **"Şeyh-ül Müverrihîn"** (Sheikh of Historians), shattered established narratives about the founding of the Ottoman State through archival documents and field research.
According to Prof. Dr. Halil İnalcık's findings:
* **De Facto and Legal Birth:** Conquered by Osman Bey in 1288, Karacahisar Fortress is the place where the Ottoman Principality gained the status of an independent state, marked by the first Friday sermon read here by Dursun Fakih.
* **Symbol of Sovereignty:** The first Ottoman silver coin (akçe), the greatest symbol of independence, was minted on this very land.
Archaeological excavations initiated in the late 1990s under Prof. Dr. Halil İnalcık's leadership brought this deep memory out from beneath the soil.
Where Are We Today? A Hidden Treasure
Today, Karacahisar Fortress is closed to visitors due to its status as an active archaeological site and its proximity to a military zone. Unfortunately, the vast majority of local and foreign tourists leave the city without seeing this hill where the foundations of an empire that ruled three continents for six centuries were laid.
A visionary city like Eskişehir should not leave this immense historical heritage idle and should transform it into a cultural route meeting international standards.
Eskişehir Live Proposes: The "Ani Model" for Karacahisar — A Vision Project
Following the example of the **Ani Ruins** in Kars, Karacahisar Fortress can become the flagship of Eskişehir tourism by establishing modern infrastructure 1–2 km behind the historical site, without damaging the ruins:
1. Prof. Dr. Halil İnalcık Visitor and Research Complex
A complex to be built at the entrance of Karacahisar Village at the foot of the fortress should serve both as an archaeology museum displaying coins and ceramics from the excavations, and as a Library of Ottoman Studies containing the works of Prof. Dr. Halil İnalcık.
2. Digital and Interactive Experience (VR / AR)
For visitors who cannot physically climb the hill, virtual reality technology should be used within the museum. Visitors should be able to experience the 13th-century fortress, the path to conquest, and the moment of the first sermon through 3D simulations using VR headsets.
3. Wooden Walkway and Historical Trail
The path from the village to the hilltop should be arranged with eco-friendly wooden walkway platforms, informational panels based on Prof. Dr. Halil İnalcık's findings, and viewing terraces overlooking the Porsuk Valley.
A Note to the Future
Eskişehir is a city that takes pride not only in its modern parks and contemporary urban fabric, but also in its deep-rooted history. Restoring Karacahisar Fortress to its deserved value means protecting the scientific legacy of Prof. Dr. Halil İnalcık and carrying Eskişehir to its rightful place on the world cultural map.
