Alameda, California

**Alameda** is a city in the U.S. state of California. It is next to Oakland and the San Francisco Bay. In 2020, about 78,280 people lived in Alameda.

Most of the city is on an island, called Alameda Island. The other large part is Bay Farm Island, which is now connected to the mainland. The third part of Alameda is Coast Guard Island, which is a military base for the U.S. Coast Guard.

## History

The city was founded in 1853, as three smaller towns. The east end was Alameda, the middle was called Encinal, and the west end was called Woodstock. The east end was incorporated as a town in 1854. The three towns became one in 1872.

When the town was built, Alameda was not an island. It was connected to Oakland at the east end. On the west end, there was an inlet of water called an estuary. People used the estuary for shipping, but it was not deep enough. To make it deeper, engineers planned to dig a canal going all the way around Alameda. In 1902, a canal was finished that separated it from Oakland.

From 1917 to 1939, there was a popular amusement park called Neptune Beach.

In the 1940s the land was filled to make Bay Farm Island. A U.S. Navy base called Naval Air Station Alameda was opened in 1940. It was closed down in 1997.
