About the place
Quoile Pondage was created by accident of engineering. In 1957 a tidal barrier was built across the Quoile to stop flooding around Downpatrick, cutting off the sea and turning a saltwater estuary into a freshwater lagoon. Over the years the new conditions drew in reedbeds, marsh plants, fish and waterbirds, and the area became a National Nature Reserve.
The riverside has a long human history too. Old quays and the preserved timbers of sailing ships line the bank, and the ruined Quoile Castle, believed to have been built around 1600, still stands at the water's edge. The whole area carries connections to Saint Patrick, whose story is woven through nearby Downpatrick.
The Quoile Countryside Centre sits beside the reserve with interpretative exhibitions about the wildlife and the barrier. Opening of the centre building itself has varied in recent years, so it's worth a quick call before you set out if you want to go inside.
