Underneath the south end of the Golden Gate bridge is Fort Point. The fort was constructed before the American Civil War to defend San Francisco Bay against enemy warships. The fort is now a national historic site which was unfortunately not open for viewing when we were there. However it does provide a unique perspective of the bridge.
Alcatraz in the distance.
The fort on the left. This was as close as we could get.
We had a perfect view of this sunset unfortunately we were in our hotel room. Turned out ok considering it was taken through our room window.
