So today I was thinking about this strange building that's located near my house. I don't really know what made me think of it, but I started wondering what was in it and what it's used for. Can anyone tell me what it's used for? It's located kind of far away from the street, so I haven't seen it in a long time and don't remember clearly what it looked like, but as far as I remember, it's just a small, one story white, square building. Right near it is some kind of short tower located right in the middle of a round platform. I remember a long time ago my dad saying it had something to do with airplanes? The building was around long before the land was ever developed and turned into a residential neighborhood. IIRC, it used to be a fenced off dirt road. The building is circled in red below, the tower and platform are right above it. If you want a closer look for yourself, Google map Lantern Hill Lane in Guilford, CT.
