History Fonte do Bastardo, located on the southern slopes of Serra do Cume on Terceira Island in the Azores, was established in the early 16th century.

The village grew around freshwater springs in Ribeira dos Lagos, which became a vital resource for early settlers and a site of pilgrimage for people from nearby towns.

The community's first church, dedicated to Santa Bárbara, was built on a promontory near Pico da Bagacina but was largely destroyed by an earthquake, leaving only its chapel and cemetery.

Fonte do Bastardo is known for its innovative spirit, introducing the island's first windmill, public bus service, bullfighting arena, and a cooperative established in 1975.

Theories suggest it may refer to an illegitimate child of a prominent settler or noble, a figure exiled to the island, or perhaps a legendary or heroic individual associated with the area's development.
