Ertugrul Gazi Museum is a small local museum in a former early-20th-century dispensary, focused on the Yörük people of the Sogut and Eskisehir region. The displays include traditional clothing, household objects, and local artefacts tied to the area that produced the early Ottoman dynasty.
Explanations are mainly in Turkish, so it is not the easiest museum for casual visitors. It is still a useful short stop if you are already following Ottoman origins around Sogut and Eskisehir.
