The Colonel Davenport Historical Foundation (CDHF) is a nonprofit volunteer group that works to preserve Colonel George Davenport’s former home and share his story with the community. The Colonel Davenport House, listed on the National Register of Historic Places, was built in 1833-1834 and is on the North end of Arsenal Island in the Quad Cities. Colonel Davenport was the first permanent white settler in the Quad Cities and built the first house in the area. The Foundation relies on volunteers to maintain and operate the house. It is open for tours from May to October, Thursday-Sunday from 12-4 p.m.
