Foster School, Trowbridge Township, Allegan County, Michigan
Location: withheld since this is now a private residence.
Foster School, built in 1888, is a private residence and for sale in 2018. It is a red brick schoolhouse with 3 large windows on each side. In front of this is a frame addition with red siding with a central front door, a large window on either side of it, and a window on each side of the addition. There is also an addition in the back, but being a private residence I didn't intrude to get a look at it. No school identification sign remains, nor does any bell tower remain.
Here's an 1888 (!!!) photograph of Foster School:
