The Canary Islands (; Spanish: Canarias, pronounced [kaˈnaɾjas]), also known informally as the Canaries, is a Spanish archipelago in the Atlantic Ocean, in a region known as Macaronesia. At their closest point to the African mainland, they are 100 kilometres (62 miles) west of Morocco. They are the southernmost of the autonomous communities of Spain, and are located in the African Tectonic Plate. The archipelago is economically and politically European, and is part of the European Union.The eight main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, El Hierro and La Graciosa. The archipelago includes many smaller islands and islets, including Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and the largest and most populous archipelago of Macaronesia. Because of their location, the Canary Islands have historically been considered a bridge between the four continents of Africa, North America, South America, and Europe.In 2019, the Canary Islands had a population of 2,153,389, with a density of 287.39 inhabitants per km2, making it the eighth most populous autonomous community of Spain. The population is mostly concentrated in the two capital islands: around 43% on the island of Tenerife and 40% on the island of Gran Canaria.
The Canary Islands, especially Tenerife, Gran Canaria, Fuerteventura, and Lanzarote, are a major tourist destination, with over 12 million visitors per year. This is due to their beaches, tropical to subtropical climate, and important natural attractions, especially Maspalomas in Gran Canaria, Teide National Park, and Mount Teide (a World Heritage Site) in Tenerife. Mount Teide is the highest peak in Spain and the third tallest volcano in the world, measured from its base on the ocean floor. The islands have warm summers and winters warm enough for the climate to be technically tropical at sea level. The amount of precipitation and the level of maritime moderation vary depending on location and elevation. The archipelago includes green areas as well as desert areas. The islands’ high mountains are ideal for astronomical observation, because they lie above the temperature inversion layer. As a result, the archipelago boasts two professional observatories: Teide Observatory on the island of Tenerife, and Roque de los Muchachos Observatory on the island of La Palma.In 1927, the Province of Canary Islands was split into two provinces. In 1982, the autonomous community of the Canary Islands was established. The cities of Santa Cruz de Tenerife and Las Palmas de Gran Canaria are, jointly, the capital of the islands. Those cities are also, respectively, the capitals of the provinces of Santa Cruz de Tenerife and Las Palmas. Las Palmas de Gran Canaria has been the largest city in the Canaries since 1768, except for a brief period in the 1910s. Between the 1833 territorial division of Spain and 1927, Santa Cruz de Tenerife was the sole capital of the Canary Islands. In 1927, it was ordered by decree that the capital of the Canary Islands would be shared between two cities, and this arrangement persists to the present day. The third largest city in the Canary Islands is San Cristóbal de La Laguna (a World Heritage Site) on Tenerife. This city is also home to the Consejo Consultivo de Canarias, which is the supreme consultative body of the Canary Islands.During the Age of Sail, the Canaries were the main stopover for Spanish galleons on their way to the Americas, which sailed that far south in order to catch the prevailing northeasterly trade winds.
