A two-and-a-half-story white house with blue trim and two white chimneys piercing the roof. A small garage is at its left with a car parked in front of it. There are bare trees in a wooded area behind it.

It was designed and built in the mid-19th century by newspaper editor and activist Horace Greeley as one of the agricultural experiments he dabbled in, testing whether concrete would make a good building material for farms. It was one of the first concrete structures in the country, and the first concrete barn. Greeley was so satisfied with the result he predicted that he would be remembered for it if nothing else.^[2]
