New Castle, Delaware

From Wikipedia.

Named Fort Nieuw-Amstel after the Dutch captured it, but it in turn was seized by the British in 1664, when they seized the whole New Netherlands Colony.

Arsenal On the Green was built in 1809, a one-story, windowless building, erected in anticipation of war with England.   At the time, it housed weapons and ammunition.   It has had many uses since then and currently is the home of the New Castle Historical Society.

In 1830, it was no longer used for military storage, but did house soldiers while Fort Delaware was under construction..  During one cholera outbreak, it was used as a hospital.  Today it also houses a restaurant/banquet facility.
