The project of the historical museum in Tongguan focuses on showing the image of the past compared with nowadays views. That is why all facilities are distributed in the whole city of Tongguan, telling stories about different adequate areas. To get to know the history of this military pass you may follow the designed paths for pedestrians or bikers. Starting point is located next to the West Gate ruins. The facility’s functions are following people’s steps on the paths – this way you are always passing through and you are never getting lost. Also each of windows/openings are oriented towards historical object or significant view. The exhibition consists of fog screens or projections that are displaying old images of those particular areas. With this idea, whole city is transformed into a museum, allowing you not only to see, but also to feel the atmosphere of the past.
