Join a guided tour of the Blair Street Underground Vaults—the oldest and deepest vaults beneath Edinburgh’s South Bridge. Built in the 1700s, these hidden spaces are only accessible through Mercat Tours.

Walk below the busy streets of the Old Town and explore a part of the city that hasn’t changed in centuries. As you move through the dark, narrow chambers, you’ll learn how these vaults were once used and who lived here.

The guide will share real stories from Edinburgh’s past, giving you a clear picture of life in the vaults—without sugar-coating the tough parts.
