Island castle built to store military surplus—exploded, burned, now touring ruins.

A set of ruins in Pollepel Island, New York, built in 1901, Bannerman’s Island Arsenal is filed here for what the record attaches to it. Island castle built to store military surplus—exploded, burned, now touring ruins. The name the accounts keep returning to is Heer of the Donderberg. The dossier holds 1 reported claim, 1 legend and 1 documented fact, with the verified spine filed separately from the lore. The site is open to visitors.

Bannerman's is the arsenal's ruin — the castle that the surplus dealer built, the '01 warehouse that's the Hudson's icon. The dealer was the buyer — the Civil War surplus that he stockpiled, the world's largest that he became. The castle was the store — the Scottish-style that was the catalog's cover, the ads that were the architecture.
The explosions were the hazards — the powder that blew the walls, the fires that the island suffered. The trust is the keeper — the stabilization that the Friends do, the tours that bring the visitors. Bannerman's is the surplus castle — the military warehouse that's the landmark, the ruin that the trains pass.
The file keeps Bannerman's: the Bannerman business, the 1901 castle, the explosions, and the preservation.
Bannerman's is the archive's Hudson file — the arsenal that's the castle.

WHY THIS FILE MATTERS
Bannerman's is the archive's Hudson file — the surplus dealer's castle.
A ruin keeps its inventory — the file's suggestion being that Bannerman's hold is the eccentricity: the arms dealer's warehouse, the castle that's the store, and the Hudson that it overlooks.
