Lanyang Museum came up with the concept of ââ¬ÅYilan as a Giant Museumââ¬Â, and promoted the first civil organization formed by local museums ââ¬ÅYilan County Family cultural museums Associationââ¬Â The buildingââ¬â¢s design is inspired by the cuestas commonly seen along the Beiguan Coast. Cuesta is a Spanish name for a geological formation in which rock layers gently slope up to an escarpment or a cliff and at this raised point the rock layers are exposed on their edges. These cuestas are unique geographical features of this region.
