This is the former Millis train station in Norfolk County, Massachusetts. For a 2011 photo from ground level, see http://www.flickr.com/photos/54690684...

As seen in that photo, the sign under the window says MILLIS. According to the caption for the flickr photo, the station was built in 1885, and had passenger service until 1967. It now houses municipal offices for the town of Millis.
