Is Sonnenberg Gardens haunted?
The record holds 1 claim, 1 legend — filed as reported, not verified. The heaviest filing is classed local folklore. The archive documents the claim; it takes no position on the ghost.
The record — long form
Sonnenberg is the widow's memorial — the nine gardens Mary Clark Thompson built after her husband died, the Queen Anne mansion on the 50 acres that were their summer place. The Japanese garden was America's first residential one; the Moonlight Garden in white flowers was the last she made.
The gardens were the world tour — the medieval walled gardens, the Italian Renaissance, the English landscape, the Victorian rockery — every style she'd seen in Europe recreated on the Canandaigua hillside. The Lord & Burnham greenhouses, the Roman bath, the Buddha from the twelfth century — the estate that was her husband's memorial in garden form.
The estate is the state's — the 1973 nonprofit rescue, the 2005 state park designation, the gardens that are still the best-preserved Victorian estate landscape in New York. The file keeps the memorial: the nine gardens, the first Japanese garden, and the widow's seventeen-year project that's still the grounds.
Sonnenberg is the archive's garden file — the nine gardens a widow built, the first Japanese garden in America, and the estate that's still the state's best Victorian landscape.
Why this file matters
Sonnenberg is the archive's memorial file — the gardens built for a dead husband, the world's styles collected on one hill, and the estate that became a state park.
A garden built as a memorial keeps its rooms — the file's suggestion being that Sonnenberg's hold is the tribute: the nine gardens Mary Thompson made, the first Japanese garden, and the hillside that's still her husband's memorial.
