Here is an Old Tower Ruins Hex Map for you. This one is much smaller scale than the previous ones, probably best to call it 30' to a hex.
This old tower ruin would be fitting for a brief adventure, some property a character inherits in a deed, or maybe standing over a dungeon entrance. It would work out pretty decently for a small skirmish battle as well.
I had a heck of a time getting the elevation contours hatch marks to come out right, I'm pretty happy with how these turned out. I made a variety of them that'll be truning up sometime in the next few days.
