Long Island’s bay houses, of which there remain only 42, were originally built in the 19th century. They stand on the fragile marshlands in the Town of Islip and the Town of Hempstead. Built and maintained by fishermen and baymen, duck hunters and recreational boaters, most of the houses that stand today range in age from 30 to 100 years old. Despite the persistent threats of high tides, erosion, and more frequent and severe storms, bay house dwellers continue to invest considerable time, money, and energy into their beloved houses. Documentary filmmaker Greg Blank discusses the unique history and culture of this world through a screening and discussion of his documentary film “A World Within A World: The Bay Houses Of Long Island”.
