Saint Agatha developed as a farming community in the mid-nineteenth century. In 1889, Bishop James A. Healy assigned a French priest to serve the predominantly Catholic community, and a parish was founded. A permanent church was built in 1890. That church burned down in August 1940. A new church, which still stands, was erected on the site in the following year. Fr. Emile Robitaille was then pastor.

The church, which is still in use, is now part of Our Lady of the Valley Parish.

The postcard bears no date and may be significantly later than the year the new church opened. There is no stated publisher.
