The Hower-Slote House was built in 1829 by James Slote on land formerly owned by John Hower. Built in the Federal style, it was the center of a working farm for more than 125 years. Reflecting a typical farmhouse of the times, the building occupies the site of Fort Freeland, a Revolutionary War defense. In 1779, Tories and Indians attacked the post, where frontier families had taken refuge. Pennsylvania troops were unable to repel the attack, and the fall of Fort Freeland prompted settlers to flee. The house is located north of McEwensville on land owned by the Warrior Run School District. The Hower-Slote property was officially listed on the National Register of Historic Places on August 22, 1979.
In 1979, the Warrior Run Fort Freeland Heritage Society entered into an agreement with the Warrior Run School District to restore and manage the Hower-Slote House and Farm. In 1980, the society entered into a management agreement with the Pennsylvania Historical and Museum Commission to manage and maintain the buildings and grounds of the Warrior Run Church.
Each year, hundreds of volunteers participate in the Annual Warrior Run-Fort Freeland Heritage Days recreating the past and interpreting the daily activities of the colonial-era pioneers who settled Central Pennsylvania. Held early in October, on the grounds of the Warrior Run High School including the Hower Slote House , expert and apprentice trades people demonstrate more than 80 skills of the 18th and 19th centuries, using authentic period tools to recreate traditional trades and pastimes. Heritage Days, has been recognized by the Pennsylvania Federation of Museums and Historical Organizations with their prestigious Award of Merit. National Geographic also has honored the event by selecting the festival for inclusion in its special edition "Geotourism Map Guide to Appalachia," as an event that sustains and enhances the geographical character of the area, the environment, culture, and heritage.
Members and friends of the society dress in authentic costumes of the period. Staged at the site of an historic military engagement, visitors may watch a re-enactment of the Battle of Fort Freeland as American Revolution patriots are challenged by the British and their allies.
