Exeter Medieval Underground Tunnels
Surveying the Exeter Underground Tunnels was an incredibly exciting project for our team. To explore and document such rich local history, right on our doorstep, was a true privilege. It remains one of the most fascinating jobs we've undertaken—combining the challenge of 3D laser scanning with the unique atmosphere of a medieval tunnel network beneath the city.
The History
14th Centuary
he tunnels were first constructed in the 1300s to house lead pipes that brought clean drinking water into the city from natural springs outside the walls.
425m Long
The known length of the tunnels stretches approximately 425 meters (1,394 feet) beneath Exeter’s city centre.
7 Access Points
Historically, there were at least 7 access points into the tunnels, many of which were sealed off during later development or for safety.
30m Deep
In some areas, the tunnels run as deep as 30 meters (98 feet) below street level, although most parts are closer to the surface.
In The Tunnels
Exeter’s Underground Tunnels are a rare glimpse into medieval engineering, winding beneath the city streets with centuries of history. Capturing their detail was a unique experience—one that required both precision and care in every step.
Data Outputs
Overlaid topographic survey data & 3D pointcluds, including realtime cloud-hosted pointcloud with information attachments.
