Fort Rua Longa
Azores, Portugal
The Fort of Rua Longa was located in the Rolo bay or cove in the parish of Biscoitos, municipality of Praia da Vitória, on the north coast of Terceira Island, in the Azores. In a dominant position over this stretch of coastline, it was designed to defend the anchorage against attacks by pirates and privateers, which were once common in this region. It crosses fire with the Fort of São Pedro a short distance to the west.
