Josiah Henson Park is the former plantation property where Reverend Josiah Henson was enslaved. This park is a historic resource of local, state, national and international significance because of its association with Reverend Henson, whose 1849 autobiography, The Life of Josiah Henson, Formerly a Slave, inspired Harriet Beecher Stowe’s landmark novel, Uncle Tom’s Cabin. The park is currently open only during a limited number of dates each season. All events are free and open to the public.

The Josiah Henson Park is part of the National Park Service National Underground Railroad Network to Freedom program.

After extensive public outreach the master plan for the development of Josiah Henson Park was approved and adopted in December 2010. This project now moves to our Park Development Division which has begun the facility planning for this park. Visit the facility planning project web page for information on the progress of this project.

Time Team America at Josiah Henson Park!

The Josiah Henson archaeological site was one of four American sites selected by Time Team America for inclusion in their second season. Time Team America brought their high-tech equipment to help Park Archaeologists learn more about a very special man in American history, Reverend Josiah Henson. “The Search for Josiah Henson“, is an over-the-archaeologists’-shoulder view of discoveries made at our very own Josiah Henson Park!

Please follow the schedule of special events for the Henson Park to find out dates when the documentary will also be shown on site.

Parks is now offering a new fieldtrip experience, “Searching for Josiah Henson” for students grades 4th – 8th with hands-on activities that include exploring current archaeological excavations, understanding soil colors and textures, mending pottery, learning about archaeological field and lab work, and mapping a mock excavation unit. Under the supervision of archaeologists, students will participate in activities that demonstrate the role of archaeologists at an historical site and how the artifacts they excavate aid in interpreting the site for visitors. Groups can register online by clicking here for the program. Parks also offers guided tours of the historic sites for older students and adult groups. Register online or contact 301-650-4373. All tours will be presented by trained guides who will make history come alive for your group. *(Title 1 schools in Montgomery County and Washington D.C are eligible for reduced admission.)

The Josiah Henson Park is the former plantation property of Isaac Riley where Reverend Josiah Henson was enslaved from 1795 – 1830. It is also a historic resource of local, state, national and international significance because of its association with Reverend Josiah Henson, whose 1849 autobiography, The Life of Josiah Henson, Formerly a Slave, Now an Inhabitant of Canada, as Narrated by Himself, inspired Harriet Beecher Stowe’s landmark novel, Uncle Tom’s Cabin.

Ongoing archaeological excavations seek to find where Josiah Henson may have lived on the site. Josiah Henson’s quarters, described by him in his autobiography as a “log hut,” and part of a “village of log huts” were located somewhere on the plantation grounds.

The house in the park that stands is the slave-owning family’s house, the Riley House, dating from 1800-1815. It is also known as the Riley/Bolten House for its later owners as well, and is listed as such on the National Register of Historic Places. The Boltens altered the house to give it a Colonial Revival appearance and put on a rear addition between 1936 – 1939.

That house features an attached log kitchen that has been dated by tree-ring analysis to 1850. Given that 1850 is after Henson’s 1830 escape to Canada, but before emancipation in Maryland, it is assumed that enslaved people, such as a cook,would have worked in the kitchen and that the cook’s family slept in a loft above the kitchen, which was known to exist, but is now removed.

The log kitchen also is the site of an interior archaeological dig, which has discovered three previous earthen floors inside the kitchen space. These earlier dirt floors indicate the presence of an earlier kitchen that stood on the very same spot as the current one.

Many of Henson’s experiences of living as a slave on the Riley plantation are vividly depicted in his autobiographies and are recreated in Stowe’s novel. Henson eventually escaped to Canada in 1830, where he established a fugitive slave community called Dawn, continued his work in the Methodist ministry, and became a speaker and writer. He led 118 from enslavement in the United States to freedom in Canada as a conductor on the Underground Railroad.

The impact of Stowe’s novel, Uncle Tom’s Cabin, should not be underestimated. Published in 1852, it broke all sales records of the time and sold over half a million copies by 1857. It inspired and enflamed the abolitionist movement in the mid-19th century and many believe it helped to propel the American Civil War.

Because of the historical associations of the Josiah Henson Park, it is among very few properties in Montgomery County that conjures up images of slavery and the slave experience. The goal for the interpretation of the Josiah Henson Park is to accurately portray Henson’s life and the Maryland slave experience as well as to explore the impact of Stowe’s novel. The realization of this goal will have a permanent educational benefit.

The Josiah Henson Park had been in private ownership for its entire history, until it was acquired by the Montgomery County Department of Parks, part of the Maryland-National Capital Park and Planning Commission (M-NCPPC) in January 2006. The building and site are protected by public ownership and M-NCPPC is committed to excellent stewardship of this resource.

The Montgomery County Planning Board held a Planning Board Work Session on December 2, 2010 where it approved/adopted the master plan and the recommended name change from “Uncle Tom’s Cabin” Special Park to Josiah Henson Special Park. Visit the Josiah Henson Special Park Master Plan web page for more information.

The Riley/Bolten House was listed on the National Register of Historic Places in 2011 for its historic significance.  It is considered to have irreplaceable cultural, material, and aesthetic value.

In 2011, the Department of Parks initiated a Facility Plan project for the Josiah Henson Park. Parks is committed to excellent stewardship of this resource because of its historical associations with slavery and the slave experience in Montgomery County. The Park Development Division is working with a team of consulting architects, engineers, and interpretive program planners to complete a Facility Plan level of work to develop, preserve, rehabilitate, restore the park site and buildings, and begin the development of a new museum at the park.

Tthe Facility Plan was approved by the Planning Board and County Council in June 2013 and work will begin in 2016 on the subsequent final design and construction phases. For information, visit the Josiah Henson Park Facility Plan Project website.

In 2008 a Historic Structure Report was written to systematically and comprehensively document the property’s origins, physical materials, and archaeological yield. M-NCPPC contracted John Milner and Associates, Inc. to complete the necessary investigations. Their experienced team developed a detailed analysis of the building and grounds.

In this document you will find information on Reverend Josiah Henson, the Riley family, and on the structures and landscape of the site. As with all historical inquiries, research is ongoing. The site also underwent a “Design Phase” that explored all of the issues surrounding the conversion of the site from a private dwelling into a public cultural resource. Parks historians are investigating the history of the Henson site on a continual basis.
