San Francisco Hyde Street Pier begins at the top of Hyde Street at Jefferson and hosts one of the main attractions in San Francisco, a floating ship museum that is operated by the National Park Service. The San Francisco Maritime National Historical Park is home to the Balclutha, an iron and steel cargo ship that operated in the late 1800s, and the C.A. Thayer, a three-masted schooner built in the late 1800s.
