This is a relatively new, nice little museum featuring tableaux from the Shenandoah Valley's past, art exhibits, a really nice collection of dollhouses and furniture, a house and gardens. The gardens were looking a little scruffy when we visited and we didn't go into the house or the art exhibit, but we really enjoyed the dollhouses and the exhibits on the Valley's past. The museum is free at certain times (I think it was Wednesday evenings when we visited).
The exhibits are at a good height for wheelchair users. Most (but not all) of the gardens, and the first floor of the house, are accessible. Bathrooms meet ADA standards, but there's no family bathroom. The other unfortunate thing was that we had to get a staff person to get the elevator up from the bottom floor.
