I live in a
house in Michigan with a tunnel that was used on the Underground Railroad. Local lore claims that over 400 runaway slaves came here to seek shelter over a 15 year period preceding the American Civil War. Jonesville is located about 100 miles from Canada's furthest Southern point and easiest crossing point--the Detroit River near Windsor, Canada. A runaway slave seeking the shortest route between the Deep South and Canada would certainly have traveled into Michigan to get to Canada. However, at a time before good maps and GPS, getting lost and crossing into Canada via Minnesota, New York, Vermont, New Hampshire, and Maine was a common occurrence.
Take yourself back in time and put yourself in a position where the color of your skin makes you immediately suspect of being a runaway slave. This immediate recognition would force you to avoid civilization and take an overland route at night following the stars to avoid capture. Uneducated black folk would need to use their wits to make it all the way to Canada. To travel 10 miles under these circumstances in a 12 hour period of darkness would be a great undertaking. Taking a zig zag course north by foot at night could take up to 2 years to reach freedom outside of the United States.
Along the way, food and shelter could be found by abolitionists and good people who disapproved of owning people as slaves. Finding these helpful locations was broadcast by subtle symbols and markings on farms and in communities that were willing to help the slaves get away. This path was cryptically known as the underground railroad, the safe houses were referred to as stations, and the people who helped them were called conductors. Many of the homes that were used as stations used hand made quilts with specific patterns embroidered into them to communicate a safe route, food, shelter plus other hints and warnings.
Munro House in Jonesville still uses 20 feet of a stone walled tunnel that ran underneath the wood framed portion of the historic house. The tunnel is about 7 feet high and about 4 feet wide. It was once over 200 feet long. It is said to have connected the basement of the brick framed portion of the Munro House with the remote carriage house that was near the St. Joseph River. The remains of the tunnel are now being used as a landing to the basement.
It is thought that as the runaways followed the St. Joseph River, they were to look for the safe house in Jonesville. Upon identifying the Munro House and possibly mingling with the Negro servants under employment of
George Munro, they were able to enter the carriage house and be undetected as they made their way into the secret room of the Munro House where they could eat and rest and obtain instructions of where to seek additional help for the remainder of their journey.
In the 1950's, a fire burned down a portion of the wood framed home. The adjoining property that held the carriage house was sold. The need to keep the properties connected by tunnel was no longer needed. The largest portion of the tunnel was filled in and a slab of cement was poured to form a sturdy foundation for the rebuilding of the damaged section of the house. The part of the tunnel underneath the unburned portion of the house was kept to use as a landing to gain interior access to the basement.
Local schools schedule tours of the house around Martin Luther King Day, Black History Month, or when their curriculum focuses on the Civil War or local history. A 45 minute tour can be scheduled on most any school day.

Munro House Bed and Breakfast
There is only one way in and one way out of the secret room. It is through a trap door in the ceiling of a room that is now being used as a bathroom. The secret room is about 20 feet long, 6 feet wide, and 5 feet tall. There is a wall with a door that divides the space into 2 separate rooms. Local lore claims that over 400 runaways spent some time with the Munro's on their way to freedom across the Detroit River to Canada. 
This space has no windows, no air ducts, and no heat. I rarely go up there because at some point someone decided to fill it with blown insulation. To open the trap door results in the outpouring of what feels like fiberglass. It is very itchy on the skin. The accumulation of years of dust and airborne fiberglass particles make it an uncomfortable place to try to breathe for a prolonged period of time. In over a decade of residence, I have only ventured into the secret room a handful of times.
Munro House became the first bed and breakfast in Jonesville, Michigan, in 1985. The innkeepers welcome tour groups to hear the stories of the early settlement, its important location on the Old Sauk Trail, and the Underground Railroad connection. Martin Luther King Day and Black History Month are typical dates when schools can schedule a 45 minute tour of the historic home and the stories it holds.
