The castle is situated at a strategic bottleneck where two major local rivers intersect, influencing its defensive design.
Historical records indicate the site was held by the Order of the Knights Hospitaller, who were granted the land in the 12th century.
The name 'Sertã' is traditionally linked to the legend of the 'Certa', a frying pan, though etymologists suggest a connection to the Latin word 'sertagine'.
Excavations have uncovered ceramic fragments indicating that the hilltop served as a human settlement long before the medieval castle was built.
The castle walls were repurposed over centuries, with parts of the stone utilized in the construction of nearby residential housing.
Castelo da Sertã is a medieval fortification located at the confluence of the Ribeira da Sertã and the Ribeira do Amioso. Its origins date back to the Reconquista period, serving as a strategic defensive point for the Order of the Hospital. The current structure features a surviving square tower and sections of the defensive walls integrated into the urban fabric of the town. Archaeological investigations have revealed evidence of Roman occupation beneath the medieval foundations. The site functioned as the administrative heart of the local territory during the medieval era. Restoration efforts have preserved the visible stone masonry while allowing for pedestrian access to the elevated viewing points. The castle grounds offer a vantage point over the historic town center and the surrounding Pinhal Interior region.
