Merchant's House Museum

The Tredwell family lived in this NoHo townhouse from 1835 to 1933 — nearly a century, with at least eight deaths inside. It's remarkably preserved with original furnishings and was the first Manhattan building to get landmark status.

The New York Times dubbed this "Manhattan's Most Haunted House," and most of the activity traces back to one person: Gertrude Tredwell. She was born in an upstairs bedroom in 1840 and died in the same room in 1933 at age 93. Her father had forbidden her from marrying a young doctor she loved, and she spent her later years as a recluse, rarely leaving the house.

The most common sighting is a woman in a brown dress moving through the rooms. Staff say their computers freeze whenever they type the name "Tredwell." Visitors hear footsteps on the stairs, piano music from an instrument that hasn't worked in years, and notice sudden temperature drops in certain rooms. In 2020, the museum launched a formal paranormal research program based on decades of reports from staff and guests.
