Pollepel Island is an island in the Hudson River that is about 50 miles north of New York City. The principal feature on the island is Bannerman's Castle, an abandoned military surplus warehouse. It was built in 1901 in the style of a castle by Gilded Age businessman Francis Bannerman VI for use as a storage facility for his growing surplus business. Most of the building was devoted to the stores of army surplus but Bannerman built another castle in a smaller scale on top of the island near the main structure as a residence.
Today, the castle is property of the New York State Office of Parks, Recreation and Historic Preservation and is mostly in ruins. While the exterior walls still stand, all the internal floors and non-structural walls have since burned down. The island has been the victim of vandalism, trespass, neglect and decay.
On-island guided tours are available through the Bannerman's Castle Trust ← This is what we did.
It was a beautiful day out and the island was really neat but we couldn't get close to the building and we had to stick with our group, which isn't the way we roll. So we all agreed that it was an amazing place but the tour wasn't thrilling and we were very underwhelmed.
After we were done with the tour the boys let me hop out of the car to wander around this old looking cemetery that we had passed on the way to the docks (They didn't get out of the car because it wasn't in the best neighborhood and they weren't into like I was). Since I couldn't stop and really look at the headstones I just took a bunch of pictures before jumping back into the car.
