Lanyang Museum is Toucheng's best building and Yilan's clearest introduction. Its sharp, sloping form was inspired by the cuestas of the Beiguan Coast, so the architecture already starts talking about the landscape before you enter.
Inside, the exhibitions work through Yilan's mountains, plain, and sea. It pairs naturally with Wushi Harbor next door, especially if you are using Toucheng as a first look at the county rather than just a beach stop.
