We toured the fort our last day in Newport. It wasn't on our top list of things to see but we had some extra time and decided to try it out. We're very glad we did. We found the fort and the tour very interesting. The fort has a lot of unique aspects including the large size, defensive strategies, etc. The fort is still be restored so much of it was still the original structure which was kind of interesting to see. The highlight of the tour was being able to go down and walk through the dark tunnels.
