Mrauk U's Archaeological Museum gathers objects from the old capital and its surrounding temples, including Buddha images, inscribed slabs, Wethali-era coins, and paintings of the city in its prime. The model of Mrauk U is especially useful before you start exploring the scattered ruins.
The museum stands near the remains of the royal palace, whose crumbling walls give the collection some context. Visit early in your stay if you want the site layout to make more sense.
