I have a big list of castles in America that I want to visit. I have already done some of them. This one is not too far away being in Providence RI. It is a very big armory. And it is currently not being used. It needs to be renovated and that is going to be expensive.
The Cranston Street Armory
It was built in 1907 and it has been used continually until recently, mostly by various military units like Military Police , Coast Guard and National guard.
There are two things about this Fortress that make it stand out. First off it is enormous. Very big for an armory. If I remember correctly the main area in the middle ( a large hall) is over 2 acres in size. One of the pictures here shows what appears to be two structures, one on the left and one on the right. But those are just the towers on each end. The trees block our view of the center of the structure.
The second remarkable thing about this Fortress is the beautiful yellow/orange stonework. It is remarkable.
