The Detroit Yacht Club was listed on the National Register of Historic Places in 2011. Construction of its fifth clubhouse began in 1921 with Commodore Gar Wood laying the cornerstone, and the building was completed and dedicated on May 30, 1923. Its distinctive Mediterranean style was designed by architect George Mason, who also designed Detroit's Masonic Temple. Built on cypress pilings driven to the river bedrock, the 93,000-square-foot structure is the largest clubhouse in the Americas. The thirteen acres surrounding it were entirely manmade from spoils taken from construction of Detroit landmarks including the Ford and Guardian Buildings, and the club continues to thrive as a jewel of the city.
