This fort was finished in 1813 and well-used during the 19th c.
It was ok to touch the flags and read the names - they were all accessible to the public.
At the other end of the park was this sculpture, which was damaged in the disaster.
But the skyline is changing, as is the footprint. The Freedom Tower is rising and while I hope it will not be too much taller, it is more beautiful architecturally than the original towers were -- and it is visible from everywhere.
