The Portsville Lighthouse is a historic house in Portsville, Sussex County, Delaware. The house is a folly, not a functional lighthouse, and is the oldest folly in Delaware. The house was built in 1932 by New York Supreme Court justice Edward R. Koch, who built the lighthouse on an existing home, store and shirt factory. Standing six stories tall, the lighthouse tower is one of the tallest buildings in inland Sussex County. The house was added to the National Register of Historic Places on September 8, 1987.^[1]
