The pagoda with a shape of a budding lotus Blue represents freedom. Green represents the fertility of agricultural cities. Brown represents archeological sites and antiques.

The symbol reflects the authenticity of the three cities that have a common history: Sukhothai, Si Satchanalai, and Kamphaeng Phet, as well as the story of Phra Ruang of the Sukhothai Kingdom, who was a builder of the city with Buddhist principles, with agriculture, irrigation, transportation, trading, handicrafts, and Thai alphabet (Lai Sue Thai).

These are the heritages that have been passed down from generation to generation and and became the Art of the Origin of Siam, which indicates the value of heritage inherited from the ancestors of the Phra Ruang dynasty until now.
