The oldest residence in the Tehachapi area was not built at its present site, but was moved there about 1900 by log rollers. Originally built in the 1870s in Tehachapi and is now a museum. The Errea House is furnished to represent a typical home from the early 1900s to the early 1940s. It is listed on the National Register of Historic Places.

The Heritage League was formed by a small group of dedicated volunteers in early 1973. The purpose was to preserve the cultural, historic, and natural resources of the Tehachapi area; to open and maintain a museum; and to serve as an educational source for individuals, schools, and other organizations. On July 4, 1973, the Heritage League opened its first museum.

The basket collection in the Milano Gallery at the Tehachapi Museum contains Kawaiisu baskets from several basketmakers. The Kawaiisu (Nuwa or Southern Paiute) used baskets for many of their everyday tasks, and the collection demonstrates that.

The Settler’s Gazette is the newsletter for the Heritage League. It is published quarterly and contains historical information, reports about Heritage League activities, and other items of interest. It is emailed to all Heritage League members, mailed to all members, and available online.

There are many opportunities to assist the Heritage League. Volunteers are always needed in the Native Plant Garden, the Errea House garden, for special events, maintenance, and repair of the museums. Also, docents are always needed for both museums. Training is provided. Contact the Tehachapi Museum or Judy Reynolds (661-331-5626) for more information.
