This small building sits about 20 feet away from a city street, with a corn field behind it (yeah, there's a corn field in the middle of the city here) and a cemetery and residential neighborhood across the street. There are no other structures nearby on this side of the street. It has one door on the side facing the street, and one on an adjoining side. There's a louvered vent above each door. The doors are locked. On the back, there are two fairly large electrical boxes with largish conduits going into the ground. I've driven past it for years and finally decided to stop and take some pictures.
It looks to me like a restroom/outhouse sort of building, because of the two doors (men's and women's?) and the vents above the doors. I can't figure out why there would be one there, though. I've looked at historical aerial photos of the area from 1993, 1962 ans 1941, and there was never anything on that side of the street other than a field. Also, I can't figure out why a bathroom would need two large electrical boxes to power it.
Any guesses? Seen anything like it before?

This door has not been opened for a while:

Best picture I could manage to take of the inside through a gap at the edge of one of the doors:
