I’m a sucker for ruins and I found this one while returning up Mystery Point Road. From where the trail returns to the the mansion, you cross the bridge of the Metro North Track and follow Mystery Point Road to the right. It’s a short way down on the right. I’ve no idea what it was, but it’s definitely not abandoned. There are clear signs that it’s under renovation. It’s probably associated with the mansion and is being restored at the same time.
What once was the interior. Now open to the elements.
A window on the interior
Three doors in a wall.
