Harris-Kearney House, Historic residence in Westport, United States.

The Harris-Kearney House is the oldest brick residence in Kansas City, a Greek Revival mansion built in 1855 for Col. John "Jack" Harris and his wife Henrietta. It was moved in 1922 to 4000 Baltimore Avenue; the west side portico was removed during that move. The Westport Historical Society restored the exterior to its pre-Civil War facade.

Colonel John "Jack" Harris and his wife Henrietta built this Greek Revival brick mansion in 1855; the family lived in it until 1881, and the Kearneys from 1870 to 1898. The military headquarters of General Curtis during the 1864 Battle of Westport was the separate Harris House Hotel, a three-story brick hotel the family rebuilt in 1848 and ran until it was torn down in 1922. In 1922 a group of women bought the mansion for $1,000 and raised $5,000 to move it to 4000 Baltimore Avenue, removing the west side portico; it opened as a museum that year, was listed on the National Register on October 18, 1972, and was bought and restored by the Westport Historical Society from 1976.

The house shows how prominent families in Westport lived and conducted their affairs during the 1800s. The rooms are furnished with period pieces that tell the story of people who shaped early Kansas City's development.

The house is open for guided tours, private tours, weddings and meetings. It stands at 4000 Baltimore Avenue, and the west side portico was removed when the building was moved in 1922, so the entrance side differs from the original layout. The interior is furnished with period pieces, many donated by descendants of the Harris and Kearney families.

The house was saved from demolition in 1922, when a group of women bought it for $1,000 and raised another $5,000 to move it to 4000 Baltimore Avenue. The move cost the building its west side portico, which was removed permanently.
