Old House (1991)

From The Dark Shadows Wiki

The back of Greystone Mansion served as the front of the OId House in the 1991 series.

The Old House was the main house of the Collins family from an undisclosed time until the year 1790 (10), during which time it was referred to as the Manor House. It was the birth and death place of Barnabas Collins, who, as a vampire, offered to restore the house when he was released from his chained coffin in 1990 (1).
