In the mid-12th century, the Moorish occupation ended: the "Al-Gharb" has been since then the kingdom of Algarve. The Algarve was a semi-autonomous area with a governor from 1595 to 1808, as well as a separate taxation system until the end of the 18th century. The coastline is notable for picturesque limestone caves and grottoes, particularly around Lagos, which are accessible by powerboat. The Algarve is a popular destination for tourism, primarily because of its beaches, Mediterranean climate, safety and relatively low costs. Praia da Marinha, Lagoa was classified as one of the 100 most beautiful and well preserved beaches of the world.
