Significance: Fort Baker, initially constructed between 1900 and 1910 and Fort Barry, established between 1905 and 1907, were the first artillery posts to be established on the north side of the Golden Gate. They were an important part of the coastal defenses of San Francisco Bay. The Baker-Barry Tunnel is a significant element of this National Register district and was an important engineering feat which enhanced the development of Forts Baker and Barry by enhancing the transportation between the two facilities.
