Indianapolis' Oldfields Estate includes the Lilly House, which was the primary residence for both the Landon and Lilly families; it retains a high degree of historic integrity. It was designed in the French Renaissance Revival style by architect and engineer Lewis Ketcham Davis and built by Brandt Brothers Construction Company between 1909 and 1913. The significance of Oldfields as a country estate comes from the combination of prominent people involved in the creation of the estate over time, and the many parts of the site that make the whole more valuable than its parts. The main home, as well as the greenhouse, garden terrace and pump house, bridges, formal gardens, statues, and other carefully chosen pieces makes the Oldfields Estate a well-preserved piece of history. As part of the Newfields campus in Indianapolis, it gives visitors an opportunity to learn and understand more about the American country estate.
