The TURASAS museum in Eskisehir is best known for Devrim, the prototype car built in 1961 and remembered as Turkey's first domestically produced automobile. The setting inside the railworks district gives the museum an industrial atmosphere that suits the story.
It is a niche stop, but a rewarding one if engineering, railways, or modern Turkish history interest you. Eskisehir has plenty of softer riverside pleasures; this museum adds a more mechanical, workshop-flavoured piece of the city.
