A series of disasters has eroded the properties in this area. In 1900, a kitchen fire destroyed the main house, and in 1905, another fire consumed the remaining structures. From 1909 to 1938, a combination of flooding, wind storms, and additional fires destroyed the rest. Here, you can now observe the ruins of the observatory and enjoy the beautiful view from this point.
