Also known locally as The Castle, it is a distinctive example of Shingle style architecture, designed as a country house by William M. Butterfield and completed in 1895.

[1] Wildwood Hall stands in southeastern Newbury, on a hillside overlooking the Connecticut River valley to the east and south.

It is set on the north side of Moore's Hill Road, on an 11-acre (4.5 ha) parcel that is formally landscaped in the immediate vicinity of the house.

The house is a 2+1⁄2-story, its first floor built out of uncoursed fieldstone, and its upper levels framed in wood and clad in wooden shingles.

At the crook of the ell, a round tower with conical roof rises above a squared porch supported by fieldstone columns.
