Mysterious Abandoned Stone House at Lake Takanassee Long Branch NJ Elberon Ross Lake 

From Weird NJ Article.

Long Branch, NJ is full of historical treasures if you know where to look. Take, for instance, the small island house in Ross Lake, the western part of Takanassee Lake. This house sits across from Monmouth University off Norwood Avenue in the Elberon section of the town. It’s just the skeleton of a two-room stone house with a fireplace. The land around this part of the lake used to be Woolley Farm and is split down the middle by the Whale Pond Brook. Owen Woolley sold 30 acres of farmland to a Dr. Dennis for $54,000 in 1886, according to The New York Times. Dr. Dennis then sold the property to P. Sanford Ross of Newark, New Jersey 10 years later in 1896.
The stones used to build this house are the same as old houses on the grounds of Monmouth University, which is considered part of West Long Branch. However, it was never owned by Monmouth University, or the famous Shadow Lawn estate that preceded the university.
