Origin and history

The aqueduct on the Guindy River is a water bridge over the river of the same name, built in the early seventeenth century to supply Tréguier with drinking water. Located between Plouguiel and Minihy-Tréguier, it is part of an 8 km supply network linking the Créven fountain to the Martray Square, near Saint-Tugdual Cathedral. Its eight schist arches, typical of local architecture, make it an emblematic piece of Breton heritage.

The initiative of its construction was taken by Adrien d'Amboise, bishop of Tréguier, who launched the works in 1610 after the plans of painter Charles Symons. The tanks of Créven (1623) and of the Place du Martray (1626) allow to date its realization. Restored in 1809, the aqueduct has been listed as a historical monument since 1931, demonstrating its historical and technical importance.

The pipeline illustrates the progress made in hydraulic engineering in the 17th century, when Breton cities are seeking to modernize their infrastructure. Its role was crucial for public health and the urban development of Tréguier, then religious and administrative centre. Today, there remains a symbol of artisanal know-how and collective water management in Brittany.
