Wat Klang Ming Mueang, originally called ‘Klang Temple’, was built in 1541 when the area was then under the control of the Lan Xang Kingdom. The important building in the ancient temple is its ‘sin’ (chapel or ordination hall) built in the 15th/16th centuries and was used for the consecrated water ceremonies to wash away the blood of war in the late Ayutthaya Period. Klang Ming Mueang Temple’s sim is built in traditional Isan style with bricks and mortar on a rectangular plot with surrounding walls, facing east. There are four chambers with a surrounding balcony and only one entrance gate. Each side of the building has five windows and the roof is tiled with earthenware shingles and decorated with holy Naga and Swan toppers. The outer walls above the windows were painted with stories of the Buddha’s past life using green, yellow and blue with black coloured lining. Inside there is a seated image of the Buddha in subduing Mara posture sitting on a plaster base.
