Lampang, also called Nakhon Lampang (, ) to differentiate from Lampang province, is the third largest city in northern Thailand and capital of Lampang province and the Mueang Lampang district. Traditional names for Lampang include Wiang Lakon and Khelang Nakhon. The city is a trading and transportation center. Lampang lies north of Bangkok and southeast of Chiang Mai. Geography Lampang city is in the valley of the Wang River, bordered by the Khun Tan Range on the west and the Phi Pan Nam Range on the east. The river, a major tributary of the Chao Phraya, flows through the city. The city lies mainly on the south side of Wang River, although the old parts of the city had been originally developed in the north side of it. Nowadays, downtown Lampang has grown in the southeast of the river along Bunyawat and Pahon Yothin Roads. Climate Lampang has a relatively dry climate relative to nearby provinces. "Winter" starts after the last rains, typically November, and lasts until March. Cold air masses from Siberia sometimes lead to nighttime temperatures below , although that is quite rare. Winter is characterized by dry, sunny, and quite pleasant days, and cool and occasionally foggy nights. In recent times, the blue winter sky is often marred by the practice of burning the fields after the harvest, as well as the smog generated by Mae Mo coal-fired power plants. Summer typically runs from March until June. The temperature could soar to in April. Late afternoon thunderstorms and hailstorms are frequent. Rainy season runs from June until November, and significant rain may occur in May as well. Being in a relative rain shadow, Lampang receives less precipitation than neighboring provinces and rarely suffers from the flooding which has plagued Chiang Mai in recent years. History Lampang was a major city in the Lanna kingdom. However, its historical prominence is largely overshadowed by Chiang Mai or Chiang Rai which were the traditional seats of government, and whose histories were well recorded in chronicles. Following decades of warfare with both the Ava Burmese and Ayudhya during the 17th-18th century, the region was in decline, severely depopulated, and subject to Burmese control. In the late 18th century, the famed marksman and Lampang native Nan Thipchang assassinated the local Burmese leader in Wat Phra That Lampang Luang, and led an uprising which led to a rollback of Burmese rule over Lanna.
