Obscura Society NYC: The Ruins of Bannerman Castle

Explore the crumbling remains of Bannerman's Island Arsenal

Join us for a guided tour of Bannerman Castle, the former island arsenal of eccentric entrepreneur Frank Bannerman VI.

On a small, rugged island in the Hudson Valley sit the castle-like remains of Francis Bannerman's ammunitions empire. Immigrating from Scotland as a baby in 1851, Bannerman began selling scrap metal from the harbors at a very young age and founded his own military surplus company when he was just 14 years old. He quickly graduated from selling scrap to canons and full-size Navy ships, and by 1900 Bannerman had such a massive accumulation of military equipment that he was required by law to move his storage outside of city limits. Bannerman relocated to Polepell Island, a small piece of land that his son had discovered while canoeing the Hudson River, where he proceeded to build his own elaborate, castle-like dwelling almost entirely without the help of architects or engineers.

Today, Polepell Island sits in an advanced state of ruin after decades of neglect.  Abandoned in 1957 following a series of disastrous occurrences, Bannerman's castle has been left to its own slow decay. Join us for a very special guided tour of the island as we explore what remains of the Bannerman family empire and delve into the history of this truly unique and fascinating site.
