These tunnels were used by slaves when they performed duties such as carrying food to their masters, bringing new tableware, taking clothing to be cleaned. These tunnels allow slaves to roam around the mansion doing their essential jobs without being seen. This created an illusion to the guests in Jefferson's mansion.
