The Baía do Refugo (literally, Bay of Scrap in Portuguese) is a body of water located on the south coast of the island of Terceira in the Azores, adjacent to the parish of Porto Judeu in the municipality of Angra do Heroísmo.
Baía do Refugo is also the name of the bathing beach that faces that body of water. The beach was formed through the erosion of volcanically-produced lava that originated in the eruption of the Guilherme Moniz volcano in 1761. The lava flowed to the sea by way of the hamlet of Serretinha in the parish of Feteira, to Porto Judeu. The path of the lava can still be traced: an area of scorched land characterized by black blocks of basalt mixed with large amounts of slag. When the lava flow neared the sea, it spread out and entered the salt water at several sites, among them the Baía do Refugo. Prior to the lava flow, the area was a small semi-sheltered cove where fishing boats would tie up. Today, the area is classified by the Government of the Azores as a Class 1 bathing beach (according to the definition spelled out in Regional Decree 1/2005/A of 15 February 2005); it has a fresh-water swimming pool and a well-equipped playground.
On 28 August 1893, a hurricane, at the time the largest storm in human memory, caused tremendous tidal surges together with punishing winds that ruined homes, churches, and barns. Ports were also battered, and a large number of vessels were lost. The damage caused by this hurricane is still visible near some sections of the coast, particularly in the former, and now abandoned, Old Church of St. Matthew of Calheta (Igreja Velha de São Mateus da Calheta) and other ruins near the Baía do Refugo.
