Chiang Mai is the hub of Northern Thailand and the Capital City of the Province of this name. With a population of over 170,000 in the city proper, it is Thailand's fifth-largest city. Located on a plain at an elevation of 316 m, surrounded by mountains and lush countryside, it is much greener and quieter than the capital, and has a cosmopolitan air and a significant expat population, factors which have led many from Bangkok to settle permanently in this "Rose of the North". Chiang Mai's historical center is the walled city. Sections of the wall remain at the gates and corners, but of the rest only the moat remains. Inside Chiang Mai's remaining city walls are more than 30 temples dating back to the founding of the principality, in a combination of Burmese, Sri Lankan and Lanna Thai styles, decorated with beautiful wood carvings, Naga staircases, leonine and angelic guardians, gilded umbrellas and pagodas laced with gold filigree. The most famous is Wat Phrathat Doi Suthep, which overlooks the city from a mountainside 13 km away. Modern-day Chiang Mai has expanded in all directions, but particularly to the east towards the Ping River, Mae Nam Ping, where Chang Klan Rd, the famous Night Bazaar and the bulk of Chiang Mai's hotels and guest houses are located. Loi Kroh Rd is the center of the city's night life.
