Uttradit has a long history developing through the years since pre-historic times. The site of the original town, then called Bang Pho Tha It, was on the right bank of the Nan River. It flourished as a port for goods transportation. As a result, King Rama V elevated its status to a province and re-named it Uttradit, literally the "port of the north".
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.
