Museum Overview

The Prosser Historical Museum features three distinct exhibit spaces:

The Front Room

The Front Room welcomes visitors to the earliest days of life in and around Prosser.  Displays are arranged like chapters in a book, including: the ancient Yakama fishing site called Taptat, dry land farming, transportation, irrigation, social life, horse culture and antique firearms...

The Parlor

The Parlor showcases the early days of the 20th Century in Prosser, a period of tremendous growth in which irrigation arrived, large commercial buildings were erected, and comfortable homes, schools and churches were constructed upon land once covered by sagebrush...

The Shrub Steppe

An interpretation of Prosser's natural Shrub Steppe environment appears in the second exhibit space. Shrub Steppe is a type of low-rainfall natural grassland that covers enormous portions of the inland American West. Although shrub-steppe is arid, it is home to a rich variety of flora and fauna.
