Experience a piece of Decatur, IL history with a tour of this amazingly restored mansion.
The Mansion was built in 1875-76 after his second marriage. The original plans for Oglesby Mansion were by William LeBaron Jenney, a Chicago architect who was best known for designing the first modern skyscraper. The Oglesbys modified the plans a great deal and hired a local contractor to build the house for them. Two of their four children were born while they lived in the house. In 1882 they moved to Lincoln Illinois and then to Elkhart where they built a much larger house on Elkhart Hill.
