This drawing, along with all the other drawings of buildings you've done for this series, makes me wonder if you've had architectural drafting training. (I can't remember if you've ever mentioned this in your streams.) This is the kind of drawing that architects do to try to sell a building design to potential purchasers. In other words, it looks absolutely real and believable. That said, it looks a lot like a small medieval castle, in its design with the towers and arches everywhere. I could imagine walking in one of the smaller, lesser known, regions of Europe and seeing this building nestled against a mountainside as either a castle open for tours or as a hostel for extended stays.
