With autumn seemingly approaching faster than expected, we decided to head down to Canandaigua for a stroll around Sonnenberg Gardens & Mansion. It’s been a few years since we were last here and its been great to see the changes that have been made. The mansion itself is a marvel, truly a spectacular property. Next time we visit, we’ll try and come earlier in the summer when the gardens are in full bloom.
The Sonnenberg mansion was originally the summer home of Frederick Ferris and Mary Clark Thompson. Frederick was a prominent New York City banker and his wife Mary was the daughter of New York State Governor, Myron Clark and a respected philanthropist who helped fund numerous charitable projects. The mansion was build between 1885 and 1887, while most of the existing gardens were developed between 1899 and 1920.
The Thompson’s had no children, so following Mary’s death in 1923, Sonnenberg was inherited by her nephew, Emory Clark. With the significant cost of running an estate the size of Sonnenberg and the financial realities of the early 1930s, Clark sold the estate to the U.S. government who developed a Veteran’s home on the site, using the mansion as staff residents.
Over time the estate and grounds began to deteriorate significantly. In 1970 a non-profit was established with the goal of purchasing, renovating, and opening the site to the public. Remarkably, by 1973 the deed to Sonnenberg was in the hands of the non-profit, generous local donations were in hand to aid with renovations, and the estate opened to the public for the first time.
Significant challenges were still to come. Most notably, a crooked CEO who stole close to half a million dollars from the organization. The State’s Office of Parks, Recreation and Historic Preservation was brought in to help in 2005.
Over the past 20 years, the organization has found its footing and has continued to restore existing elements of the mansion and gardens and add new features and offerings.
