The Antoine LeClaire House is a historic building located on the east side of Davenport, Iowa, United States.

[1][2] Antoine Le Claire was an interpreter for the U.S. Government stationed at Fort Armstrong on Rock Island on the Mississippi River.

In 1832 he was the interpreter for the treaty signing between the Sac (Sauk) and Meskwaki tribes and the United States after the Black Hawk War.

The tribes gave Le Claire two parcels of land in Iowa, one at the top of the Rock Island Rapids and one below.

[3] Le Claire agreed to build his first house on the location where the Black Hawk Treaty was signed.

The Reserve is one of the parcels deeded to Le Claire by the tribes and covers much of the east side of Davenport south of Locust Street.

The house, and others being built by Davenport's wealthier citizens, shows the progress the city had made in the twenty years since its founding.

Previously there had been a friendly rivalry between Cosgrove and Davis after the later had a new rectory built at Sacred Heart Cathedral, where he was the rector, because it was larger and more modern.

The LeClaire House is a two-story, brick, 14-room Tuscan Italianate mansion on the top of a bluff 125 feet (38 m) above the Mississippi River.

The estate also contained carriage barns, a summer kitchen, an ice house, and a plum grove.

The area will have a resource by which future generations of residents can develop a better understanding and appreciation of Davenport's important role in the settlement of not only eastern Iowa, but also the entire state.

The rehabilitation of LeClaire House, especially due to its visually prominent bluff-top location, will stimulate the interest of both residents and tourists alike in local history.

The quality of life for the neighborhood in particular and community pride in the area as a whole will be enhanced when the highly visible homestead of the city's co-founder is fully restored and in use.

The City will have a self-supporting community/local history interpretive center in the central city providing a unique service to non-profit groups, neighborhood associations, and the general public.The LeClaire House is historically significant both in its architecture and the importance of Antoine Le Claire to the local community.
