Fodor's Expert Review Underground Passages

Exeter's Underground Passages, which once served as conduits for fresh water, are the only medieval vaulted passages open to the public in Britain. They date to the mid-14th century, although some were enlarged by the Victorians. An exhibition and video precede the 25-minute guided tour. Many of the passages are narrow and low: be prepared to stoop. The tours often sell out during school vacations, so come early. Children under five are not permitted in the tunnels.
