Due to its remote location, Nan is not the kind of destination most travellers are going to stumble upon. And its largely featureless downtown isn't going to inspire many postcards home. But if you've taken the time to get here, you'll be rewarded by a city rich in both culture and history. Many of Nan's residents are Thai Lü, the ancestors of immigrants from Xishuangbanna, in southern China. This cultural legacy is seen in the city's art and architecture, particularly in its exquisite temples. A Lanna influence on the town can also be seen in the remains of the old city wall and several early wát.
