" Without question, this spacious walled garden is a nationally significant historic landscape that is worthy of preservation. In its day, Miss Sinkler's garden exemplified design principles and stewardship principles that were common in many estates during the "Country Place era" in American landscape architecture. The garden's association with two prominent American designers of the period - architect Wilson Eyre, and interior designer Henry Davis Sleeper - also heightened its stature in the nation...this enchanted, theatrical setting was tailor-made to suit the unique personality, avantgarde taste and refined lifestyle of their friend and client, Miss Sinkler. "

Over the past six decades, however, many of the gardens character defining features have been lost or degraded. Fortunately, site and archival research have revealed that there is ample documentation - in the form of historic plans, photographs, aerial views and descriptive accounts - to accurately restore the detail, form and character of Miss Sinkler's garden with only a limited degree of conjecture. To the degree possible, the restoration program highlights the years that immediately precede and follow Miss Sinkler's receipt of a special achievement award (1933) from the prestigious Pennsylvania Horticultural Society.
