Twelfth Night (also known as Epiphany Eve) is a festival that traditionally takes place on the last of the 12 days of Christmas, marking the coming of the Epiphany. The celebration will include the customary Twelfth-Night Cake. The person that finds a bean in a slice of cake gets a crown and a person that finds a clove in a slice of cake gets a jester hat for the night. In addition to the cake other lite refreshments will be served. Traditional colonial music and Christmas carols will be provided by, a Choral group representing the Unitarian Church, and Fiddler Beverley Conrad.

Ron Blatchley as Joseph Priestley will conduct chemistry demonstrations in the Pond Building at 4:30 and 5:30. Seating is limited and tickets for each session are available in the Visitors Center.

The Joseph Priestley House will be open for self-guided tours with docents dressed in period costumes in each room to answer any questions. The house will be traditionally decorated with pine, holly, and candles.

When guests arrive at the Visitor Center they will be escorted by lantern to the Priestley House and Pond Building.
