Berlengas
The Berlengas archipelago is a group of small islands 10 to 15 kilometers off the Portuguese coast, west of the town of Peniche in Oeste region. These islands were traditionally known to British mariners as "the Burlings".
History
Human occupation on Berlenga Grande (the only habitable island) dates back to antiquity: the islands are referred to in Ptolemy's Geography as Λονδοβρίς (Londobris). Much later it was referred to as the island of Saturno by Roman geographers, and was visited successively by Muslims, Vikings and pirates/privateers from England and France.
In 1513, with the support of Queen Leonor, monks from the Order of São Jerónimo established a settlement on the island to offer assistance to navigation and victims of frequent shipwrecks. The monastery founded there (the Monastery of the Misericórdia da Berlenga), remained until the 16th century, when disease, lack of communication (due to constant inclement weather) and regular assaults by pirates and privateers (from England and France), forced the monks to abandon their service on the island.
