Fort Point, once called  

Did You Know?
In 1882, the fort now known as Fort Point was given the name "Fort Winfield Scott", a name it retained for four years before being downgraded to a sub-post of the Presidio. In 1912, the name was reused for the new coast artillery post at the Presidio, today's Fort Scott.
