Descend into one of Exeter’s most fascinating hidden treasures at Exeter’s Underground Passages. These medieval vaulted water tunnels, built in the 14th century to bring clean spring water under the walled city, are unique in the UK. Visitors begin their journey with an interactive interpretation centre, featuring exhibits such as a talking medieval figure, a video fly-through, artefacts from archaeological digs, and a full-size model of the passages.
Then, it's a guided 25-minute tour through the dim, vaulted passageways—lit for safety but retaining that sense of mystery. Tours run regularly (book ahead for weekends and school holidays), and while the underground part is not suitable for under-5s or those who find low, narrow spaces difficult, the exhibition is accessible. Whether you’re into history, architecture, or just looking for a cool escape from the city streets, this is an unforgettable experience deep beneath Exeter.
