This top-class museum has three floors that walk you through all aspects of Shānxī culture, from prehistoric fossils to detailed local opera and architecture exhibits. All galleries are imaginatively displayed and some contain good English captions. Take bus 6 (¥1) from the train station, get off at Yīfén Qiaoxi (漪汾桥西) bus stop across the river and look for the inverted pyramid.
A new geology museum (shaped like a UFO) was being built next door at the time of research.
