On the 2nd floor are exhibits on Nan history, archaeology, local architecture, royal regalia, weapons, ceramics and religious art. Of the latter, the museum’s collection of Buddha images includes some rare Lanna styles as well as the floppy-eared local styles. Also on display on the 2nd floor is a rare ‘black’ elephant tusk said to have been presented to a Nan lord over 300 years ago by the Khün ruler of Chiang Tung (Kyaingtong).
