This is a historic site that is nice. Good interpreter told us about it and offered to take pictures of us. YOu can’t climb it and the keepers houses aren’t open yet but eventually it will be better. The most unique feature here is the boundary marker separating Maryland from Delaware in front of the tower. It was nice to stand in 2 states. What’s even more unique about it is that it was surveyed when Delaware was Pennsylavania so the marker is from the 1700s and has William Penn’s crest on that side and the Calvert family crest on the other.
