The Devil’s Tower is located in Rio Vista and is an upscale neighborhood in the southern section of Alpine. The Tower is a stone clock tower that is claimed to be haunted, that was originally built by sugar baron Manuel Rionda (1854– 1943) in order to allow his wife to see New York from the New Jersey side of the Hudson River. His mansion was the biggest one on the Palisades, with a mansion on the cliffs where the present-day Alpine Lookout is located. The legend has it that when his wife saw him with another woman, she committed suicide by jumping off the tower. After becoming upset over his wife’s death, Rionda stopped all work on the tower. In reality Harriet Rionda died of natural causes in 1922 and was interred nearby for approximately 20 years; her coffin was moved to Brookside Cemetery, Englewood. The estate was later sub-divided into 197 housing sites consisting of miles of roadway, infrastructure, and related facilities in the mid-1980s but was mostly woodlands through the 1970s.
