Not necessarily abandoned, but certainly neglected.
Most one-room schoolhouses that you’ll find in Vermont are wood frame construction and wood clapboard. For that reason, this Greek Revival one-room schoolhouse of marble construction at the intersection of Route 73 and Route 30 in Sudbury, VT jumps out at the passersby. Known as the District No. 3 School or the Sudbury Hill School, it dates to 1829 (for alterations) and ca. 1821 (original construction).
Today the school appears secure, dry, and safe, but vacant. Do you know who owns or uses the school? If you’re interested in exploring the school and looking in the windows, look at these photographs and captions.

The little schoolhouse sits on the side of the road with a message board, but no news to report in November 2015.

Sudbury School No. 3. Look at the gable end and you can see that the roof might have been raised (hence the 1821 and 1829 construction dates).

Windows were not needed on the north side. At back of the school are the attached privies.

The bank of windows was likely added later when school standards were developed. Look closely and you can see an original window (now filled in) to the right of the window bank and on the front left of the gable end.

The west bank of windows.

Desks, books, miscellaneous items, chalkboard, as see through the window.

The schoolhouse appears to have been used in the last half century, based on the desks and the heating duct. Now it serves as storage.

More of the same.

To the privies.

Marble fieldstone construction.

What do you think? Beautiful, yes? Would you rather have a vacant/neglected building like this converted to a private residence, a town office, or a museum that is open sparingly?
