Sukhothai, the dawn of Thai civilization, stands as a testament to the cultural and political beginnings of Thailand. Founded by Si Inthrathit in 1238, it flourished during the reign of King Ram Khamhaeng, who is credited with creating the Thai alphabet and establishing Theravada Buddhism as the state religion. The historical park, now a UNESCO World Heritage Site, preserves the majestic ruins that echo the glory of the kingdom's past, inviting visitors to wander through the remnants of palaces, temples, and monuments, and to immerse themselves in the story of a bygone era.
