Within the enclosure are brick ruins, chedi bases and remains of Wat Phra Si Rattana Mahathat. The area is quiet and largely undeveloped, with walking paths, information signs and mature trees. It is suitable for walking, photography and viewing historic structures along the Nan River.

Mueang Kao Phichit is the site of the original town of Phichit, established during the Sukhothai period and later important in the Ayutthaya period. The fortified settlement with earthen walls and moat served as a strategic administrative center on the Nan River controlling river routes in the lower north. Archaeological remains including temple ruins and city walls reflect its role from the 14th century onward before the town center was later moved to its present location.

The site is a protected archaeological site representing the historical urban heritage of Phichit Province. It preserves religious architecture and city planning traditions of the Sukhothai-Ayutthaya era and remains a place of local historical identity and educational value for visitors learning about the region's past.
