Serra de Santa Bárbara is the peak of an dormant volcano in the western part of the island of Terceira, Azores, Portugal.
[2] It is named after the village located on the coast to the south, Santa Bárbara in the municipality of Angra do Heroísmo.
[3] The peak lies on the south rim of the Santa Barbara Caldera which is approximately one kilometer wide, having two smaller peaks in the center of the caldera.
[4] The upper slopes and the floor of the caldera are covered by holly and juniper forests,[5] almost all of which are protected in the Nature Reserve of Serra de Santa Barbara e dos Mistérios Negros.
[6] In 1761 a portion of the volcano erupted, and according to local religious lore, the villagers took a holy relic up to the erupting lava, and the lava stopped.
