Overview

History & significance

Ogwen Fish Weir is a post-medieval fish weir located in the Ogwen Valley in Conwy, Wales. The structure represents a form of medieval and early modern fishing infrastructure designed to trap and direct fish, particularly salmon, in the river system. Fish weirs of this type were economically important features of Welsh rural subsistence and agricultural economies, providing a reliable protein source for local communities and manorial estates. The weir's physical remains exemplify the engineering practices employed in river management for fishing purposes during the post-medieval period, though the exact chronology of this particular structure remains subject to archaeological interpretation.
