Hampton Roads
Beginning in 1917, as the United States became involved in World War I under President Woodrow Wilson, formerly rural Sewell's Point became the site of what grew to become the largest Naval Base in the world which was established by the United States Navy and is now known as the Naval Station Norfolk.
