The corner building was constructed in 1862 with an addition in 1887 and another in 1894. I am not totally sure but it may be the oldest remaining school building in the City of Cincinnati. The oldest remaining Cincinnati Public School is from 1868.
The design is a fantastic eclectic composition of Italianate, Queen Anne, and 2nd Renaissance Revival.
This is just one building on the East Over the Rhine ARCHITREKS tour. But it may be my favorite.
