Christ Church Mission, also known as the Anvik Mission, is a historic Episcopal church mission in Anvik, Alaska. It is located near the former confluence of the Anvik and Yukon Rivers, about 2 miles (3.2km) below the present confluence. There are four buildings that survive from what was once a larger complex. The largest is the main mission building, is a 36-by-72-foot (11m ×22m) structure built in 1932. The oldest building is the church, which was built in 1892, and was moved to the present site when river erosion threatened the previous one.[2]
