Ancient Ruins In The Twin Cities?

Ancient Ruins? 1885 this building was built. Does over 100 years count as ancient? That's debatable for sure. So what and where is this place in the Twin Cities....Especially you locals who are familiar with the area. I can assure you, it is in the Twin Cities metro area. I discovered in using one of the photo areal sites, local.live.com. I was looking at a particular place from the satellite view when I discovered this odd shaped remains of a building. If you think this photo looks mysterious in this photo, try looking from a satellite image and try to figure that out. As I wasn't sure exactly what I was looking at....There it was, I had a mission, I had a quest, I had to discover it for myself....I will let you discover it with me.
