The horse stables at Collinwood was a large, two-story wooden enclosure on the south end of the property separated from the main house. Included in the structure was a carriage house containing several antique Hansom cabs and sleighs. The second floor area of the stables was cluttered with various pieces of furniture that the Collins family had collected over the years. In 1810, Charles Collins kept his personal steed, Dubloon housed inside of the stables. He used Dubloon as a weapon of vengeance against a clergyman named Reverend Strack, whom he blamed for the death of his lover, Angelique.
