The Marshfield District of Coos Bay is the historic central downtown and business district of the city. Old Marshfield and its surrounding neighborhoods were what comprised the original Coos Bay before the annexations of Empire and Eastside during the 20th century. The Marshfield District contains many buildings listed on the National Register of Historic Places, such as the Carnegie Library, Chandler Hotel, Egyptian Theatre and Tioga Hotel. The waterfront area of the Marshfield District has a boardwalk with a city dock, bicycling trail and pavilions featuring historical and interpretive displays.
