The grounds at this 52-acre estate are a magnificent example of late-Victorian gardening and design. The rose garden overflows with 4,000 bushes; the other themed plantings include Japanese, pansy, blue-and-white, and rock gardens. An early-1900s conservatory houses the orchid collection and other exotic plants. The stunning 1887 Queen Anne mansion was built as a summer home by a wealthy New York City banker and his wife, who became Canandaigua's biggest benefactress. The library, the couple's favorite room, looks out on the Italian garden. The great hall features a massive leaded-glass window and an 1874 Steinway. Walking tours are offered weekdays at 1 and weekends at 10 and 1 from Memorial Day through September.
