Russian Village District, Historic district in Claremont, United States

Russian Village District is a group of 15 folk architecture style houses at South Mills Avenue and East Cucamonga Avenue in Claremont, California. Built mainly by Polish immigrant Konstanty Stys and neighbors, the houses use local field stones, railroad car sides, and debris from the 1933 Long Beach earthquake. Only one house was designed by a professional architect.

Polish immigrant Konstanty Stys began building on South Mills Avenue in 1923, starting with a garage where his family lived until his own stone house was finished in 1925. During the Great Depression he sold lots cheaply, often with no down payment, and helped unemployed friends raise houses from field stone, railroad car sides and debris from the 1933 Long Beach earthquake. Neighbours called the result the "Russian Village", assuming Stys was Russian. The district was listed on the National Register of Historic Places in 1978.

Residents nicknamed the houses the "Russian Village" because they assumed builder Konstanty Stys came from Russia; he was in fact Polish. Stys, a steelworker turned construction worker, sold parcels cheaply to unemployed friends during the Great Depression and helped them build homes from salvaged materials.

The district runs along South Mills Avenue at East Cucamonga Avenue, and several parcels straddle the Claremont–Montclair line in San Bernardino County, so addresses on the same block fall in two cities. The houses are private homes; view the stone facades, railroad-tie window supports and salvaged materials from the public street.

Only one house in the district was designed by a professional architect: Peter Ficker drew the 1933 house at 330 South Mills Avenue to settle a debt to Stys. Stys misread the plans and began building on the wrong part of the lot, so the owner sold it back to him.
