Collinwood Mansion Collinwood Mansion is a gloomy forty-room mansion located near Widows' Hill. The house was built in 1795 by Joshua Collins. The east wing of Collinwood was closed off around 1916 and most of the house fell into disuse. Elizabeth Collins Stoddard successfully petitioned to have the property tax reduced due to most of the house being closed. The house was more of a liability than an asset and by 1967 it was only Collins-owned property without a mortgage. The road leading up to Collinwood from town is steep, with many turns. Several people have died going down the hill in bad weather. Collinwood is reputed to be haunted by Josette Collins as well as several other members of the ancient Collins Family. Several actual mansions were used for Collinwood. The Carey Mansion (Seaview Terrace) in Newport, Rhode Island, now part of the Salve Regina University campus, was used for the original series. The Lyndhurst estate in Tarrytown, New York was for both films. In the 1991 NBC version, Greystone Mansion in Beverly Hills was utilized, with nearby Griffith Park as the forest surrounding Collinwood. The Old House The Old House was once the provincial mansion of the Collins family up until 1796. Located on the Collins estate near Widows' Hill, it was formerly known as Collinwood. Joshua Collins was the patriarch of the last generation of Collins family members to be raised there. In 1796, construction was completed on a larger family home on the same property and this first known as the Great House. Later, it would come to be known as Collinwood. When it was first built, the original family mansion began to be referred to as the Old House. With the passing of generations, this off-hand phrase became the official nomenclature for the regal estate. The filming location was the former Spratt Mansion on the Lyndhurst estate, destroyed by fire in 1969. Originally built in the 1850s, it was acquired by Russell Hopkins in 1907. Called
