During the 1875 Centennial celebration, artifacts connected with the events of April 19th were put on display for guests to witness. Then President Ulysses S. Grant viewed the Major Willard Buttrick Powder Horn, 1774, which was listed in a souvenir program issued for the occasion along with other witness artifacts to the day’s events.

The Willard Buttrick powder horn was donated to Minute Man National Historical Park by the Buttrick Family in 2018. After the park acquired the horn, it was conserved by National Park Service staff and then exhibited at the Buttrick Mansion (North Bridge Visitor Center). The entrance to the Buttrick Mansion is directly across the driveway from the foundation of Willard Buttrick’s home.
