The Eldridge Mansion is a large residence in the Chateau Style, completed in 1927. The homesite was the ancestral home to the Eldridge family since early Pacific Northwest pioneer and patriarch Edward Eldridge and wife Teresa stalked a donation land claim to the property in 1853. Since then, the site has seen three mansions built on the grounds. Teresa Eldridge was the first known female Caucasian resident in the region and their daughter, Isabella, was the first known Caucasian child. Edward Eldridge held many local political offices and was an outspoken advocate of women’s rights. The existing mansion was commissioned by Edward’s only son, Hugh, and designed by F. Stanley Piper.
