The chateau of Azay-le-Rideau supposedly inspired this three-story red sandstone dwelling. The irregular plan includes an attached, similarly styled carriage house connected through a small courtyard. The steep slate roof bristles with crockets, finials, roundel dormers, and corner towers, although much carved sandstone decoration has disappeared.
Thomas B. Croke was a schoolteacher and clerk who invested in railroads and agriculture. His experiments with irrigated farming on 3,500 acres north of Denver in what is now the suburb of Northglenn proved remunerative enough to pay for this $100,000 mansion. Later it became the residence of Thomas M. Patterson, owner of The Rocky Mountain News and a U.S. senator, and then of Patterson's son-in-law, Richard C. Campbell. Several deaths here have inspired persistent rumors that the house is haunted.
