This dusty museum has exhibits on the geology, history and culture of Lombok and Sumbawa. There’s an interesting collection of prehistoric pottery, massive bronze kettledrums and a captivating assortment of kris (traditional daggers) and songket (silver- or gold-threaded cloth). For an extra 40,000Rp, check out gold swords and jewellery that once belonged to Sumbawan sultans and Javanese kings.
