Per the Metro Parks Tacoma website “the Pagoda was built in 1914 as a replica of a 17th century Japanese Lodge. It was originally a waiting room for streetcars. Now this magnificent structure functions as a rental facility for weddings and other private parties as well as a venue for garden shows, lectures and concerts.”
