Update: I photographed it another time in 2012. The high school was finally demolished in the summer of 2019.
Like much of America, Kirksville ditched its historic, pedestrian friendly high school for a sprawling suburban, car oriented building on the outskirts of town in the 1950’s. The old high school has sat empty for decades.
The interior looks like a cave, with actual stalactites hanging from the ceiling, the result of decades of water damage. I once went to a student art show here back in college; each person took their own room and literally hung their works on moss covered walls.
