What is recorded here

Lucan, Ireland: A medieval fish weir stretched the Liffey between Lucan Demesne and Coldblow, drawing royal writs and jury verdicts over who owned which share of the catch. Hugh de la Felde, John de Hausteyd, Ralph Pipard and the King’s treasurer all clashed around the same water, while jurors complained the weirs had grown too high and blocked boats, firewood and fish. The structure is gone now, but the river still passes the place where men argued about ownership, measurement and hunger.

A stone built weir, built to resist floods was erected at the head of the watercourse at Balrothery near the gravel pits. The Dodder River was diverted at this stone weir and an artificial channel was constructed which carried the required water eastward to join the river Poddle. This was removed during road construction (Keeley unpub).
