The provincial seal shows the mondop at the temple Wat Phra Thaen Sila At, in Baan Phra Thaen in the Laplae district. The main item of worship in the temple is a laterite block, which is believed to have been used by Buddha to seek enlightenment. The mondhop is built upon this block.
The seal was first designed in 1940, later a garuda as the symbol of Thailand and the name of the province were added.
The provincial tree is the Teak (Tectona grandis).
