and Historic Preservation and is mostly in ruins. While portions of 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. Several old bulkheads and causeways that submerge at high tide present a serious navigational hazard. On-island guided hard hat tours were recently made available through the Bannerman's Castle Trust. The castle is easily visible to riders of the Metro-North Railroad Hudson Line and the Amtrak Empire Service and Adirondack lines. One side of the castle, which carries the words "Bannermans' Island Arsenal", is also visible to southbound riders. Sometime during the week before December 28, 2009, parts of the castle collapsed. Officials estimate 30–40 percent of the structure's front wall and about half of the east wall fell. The collapse was reported by a motorist and by officials on the Metro-North. On April 19, 2015, the island was the destination of a kayak trip taken by Vincent Viafore and his fiancée. Viafore drowned, and his fiancée was charged with his murder. On July 24, 2017, she pled guilty to criminally negligent homicide and served a short time in prison. On June 28, 2015, the public art piece Constellation by Beacon-based artist Melissa McGill debuted on and around the castle ruins. The work consists of seventeen LEDs mounted on metal poles of varying heights, which when lighted for two hours each night are intended to create the appearance of a new constellation. Currently (2021) the island is under the care of "The Bannerman Castle Trust, Inc." which is a non-profit organization of “Friends” of volunteers who work with the New York State Office of Parks, Recreation and Historical Preservation. The Trust is dedicated to pooling resources and funding to stabilize buildings on Pollepel Island and to raise awareness and educate the public and governmental organizations about the island's value and history. The Trust is making the island safe for volunteers and the public to enjoy as an educational, cultural, historic and recreational facility that promotes historic tourism in the Hudson Valley. Bannerman Castle Trust In popular culture In literature Bannerman Castle by authors Barbara Gottlock and Thom Johnson was released through Arcadia Press in August 2006. The book contains almost 200 vintage photographs, and the text documents the island's growth and decline. Proceeds from the book go to the Bannerman Castle Trust
