In 1914, the West Side Tennis Club moved from Manhattan to Forest Hills Gardens. They constructed the Forest Hills Tennis Stadium, a stadium with approximately 13,000 seats, in 1923. The U.S. Open and its predecessor national championships were held there until 1978, making Forest Hills synonymous with tennis for generations. Forest Hills also had a golfing presence for a short time. The Queens Valley Golf Club started constructing a golf course in the neighborhood in 1922 and it was open by 1924. However, the club was closed in 1938 so that developers could build housing atop the site of the course.
