The passages were built to protect lead pipes that transported spring water to Exeter’s city center, a sophisticated system for the 14th century.
During the English Civil War, the passages were used by defenders to reach outer city defenses safely.
The tunnels were largely forgotten and neglected for centuries until restoration efforts began in the 20th century.
The stone vaulted ceilings were hand-constructed by medieval masons to support the weight of the city streets above.
The passages are one of the few examples of medieval subterranean water infrastructure preserved specifically for public heritage education.
Exeter’s Underground Passages are a unique network of medieval vaulted tunnels constructed during the 14th century to house clean water pipes supplying the city. These are the only known passages of their type in the United Kingdom. Originally built to protect lead pipes that brought fresh water from springs outside the city walls to public fountains, they became vital for infrastructure and public health. Today, visitors can explore sections of these tunnels via guided tours that reveal the original masonry and historic water management systems. The tunnels remain located directly beneath the city center, offering a literal sub-surface look at Exeter's urban development history. The site operates as a dedicated heritage attraction focusing on medieval engineering and subterranean history.
