OKLAHOMA CITY (AP) -- The National Register of Historic Places is adding four more Oklahoma properties on its list of historically significant properties.

Ardmore's municipal building known as Heritage Hall and the Hardy Murphy Coliseum in Ardmore are two of the properties.

Also being added are two properties in and near the Jackson County town of Olustee, southwest of Altus.

The tiny Olustee library and park and the Cross S Ranch Headquarters near Olustee are being put on the list.

The ranch headquarters was built in 1891 and is all that remains of the ranch that was established in 1880.
