There's a wonderful piece of history in the Bay Area that's just about a secret. Up in Marin County, within the Point Reyes National Seashore, along Drakes Bay is Drake's Cove. It is here, in 1579, that Francis Drake landed, met with the Coast Miwok, repaired his ship, resupplied and then completed the first successful trip around the world.
This was before Roanoke, before Plymouth, before Jamestown.
It happened here.
As part of a "cold war" with Spain, Drake had entered the Pacific Ocean, raided Spanish towns and ships and acquired 26 tons of silver and other treasure.
Seeking a way home, he headed north looking for the Strait of Anian - the expected water passage across the top of North America. Failing that, he turned south from Oregon seeking a harbor to repair his ship. He found the Oregon and Northern California coasts treacherous to a small wooden ship. The first decent harbor he found was at Drakes Bay.
