Landmark, Scenic Lookout, Castle
- It's sort of like the Gravensteen in Ghent. #VisitFlanders
- Designed by Lieutenant Colonel Jonathan Williams it was constructed of sandstone with walls measuring 8 feet thick at the base. The castle was designated a City landmark in 1967.
- The circular castle, designed by the head of the Army Corps of Engineers in 1807, was used as a jail for Confederate troops and AWOL Union troops during the Civil War. Read more on MetroFocus
- Cool national park small but informative really nice views of the harbor and city.
- You can only enter the roof on a guided tour every hour. The last tour on weekend is 5:30pm.
- It used to be a prision, good a nice view but still a prision. :(
- More of a Fort than a castle
- Every hour (on the half hour) go to the Ranger table for tickets to the rooftop tour (which will be an hour later but there is plenty to do) on the weekend. It's worth it for the views of NYC.
