That's an awesome looking fort! I love those old forts, too; Fort Delaware is nearby that I have gone to quite frequently, and Fort Mifflin in Philadelphia and Fort McHenry in Baltimore are fun, too. Fort DuPont (very near Fort Delaware) no longer stands, but there are some walls and small structures still standing.
Thanks for sharing! I love seeing these.
Those all sound like places I would love to visit
I hope the NEw year has started well for you
