To draw a parallel with the melding of mountains and sea in Yi-lan, the permanent exhibits at the Lan-yang Museum, beginning on the fourth floor and spiraling down from there, focus respectively on the themes of mountains, lowlands, sea, and time. In addition, there is also an introductory exhibit room near the entrance.
為了類比蘭陽平原山海交融的地理空間，蘭博館常態展的樓層設計，由 4 樓盤旋而下依序為：山、平原、海、時光廊，以及小巧的序展廳。
