Arden, Historic mansion in Woodbury, US.

Arden is a mansion in Woodbury located at the summit of Mount Orama, overlooking the Ramapo River Valley. The property contains approximately 97 guest rooms, an auditorium, outdoor pool, and private lake within its 450-acre grounds.

Railroad magnate Edward Henry Harriman acquired the property in 1886 and expanded it significantly during the early 1900s. The residence grew from an initial purchase into a large estate with extensive buildings and grounds.

The mansion features a medieval-style music room and displays photographs from the 1899 Harriman Alaska Expedition by Edward Curtis. These spaces reflect the owner's passion for history and exploration.

The location is about 40 miles from New York City and is accessible by local road connections. The grounds are expansive, so plan for adequate time to explore the various areas and buildings.

The building was constructed using stones extracted directly from the mountain on the estate during the early 1900s. This approach tied the architecture closely to the natural terrain of the location.
