In 1972 historians explored the old city area of
Mueang Phrom Phiram. They found remains of the city wall,
Chedi basements and
Sukhothai Celadon on Phra Ruang Road from Sukhothai in Tambon Si Phirom and Dong Prakham. As that road continues eastward to Wat Bot and Nakhon Thai, the historians assumed it was the road for transportation between Sukhothai and Bang Yang. Also King
Trailokanat moved his troops passing Phrom Phiram to Phichai for the war with King
Tilokaraj of
Lanna. The old location of Phrom Phiram was in Tambon Matum. It was created as Phrom Phiram District in 1895. The district office was moved to the right bank of the
Nan River at Ban Yan Khat around 1950. When the government built the northern railway passing by Phrom Phiram District, the district office was then moved to Ban Krap Phuang (now named Ban Phrom Phiram), 500m from Phrom Phiram railway station. The district office was renovated in 1960. The present office was opened in 1976. == Geography ==
