Sra Luang
Sra Luang was the old town of Phichit on a former course of the Nan River. Its brick walls and moats enclosed a settlement that served as an important centre of the Sukhothai kingdom. At its heart stood Wat Mahathat, with a bell-shaped stupa, an assembly hall and a surrounding moat. The monastery continued in use under Ayutthaya, when further buildings were added. Its river setting placed the town on a waterway linking the northern valleys with the central plain.
