The Toppenish Murals began in 1989 with the inaugural mural titled "Clearing the Land". The idea was formed when state seed money was distributed to small communities in correspondence with the State of Washington's centennial celebration.
A group gathered and brainstormed the idea of historical murals and hosted the first annual MURAL-IN-A-DAY event in which an entire wall sized mural is painted in one day by a dozen or more artists. Since the first mural was completed a Mural Society was formed and the organization has completed 75 additional murals, including a single mural in a day each year on the first Saturday in June. Hundreds gather to come and watch paint dry.
