Afternoon Teas at the Donelson House

Teas are social events, lasting from one and one-half to two hours. As with the traditional English Afternoon Tea, a light meal is served, generally consisting of finger sandwiches, scones, vegetable trays, and desserts. Reservations are required and the teas are only held on certain dates.

About the teas

Pioneer School

Each summer a Pioneer School is conducted to give children the experience of going to a one-room school. In addition to learning activities, as they would have been in 1875, several outdoor activities are also planned to engage the students attending the pioneer school.
