Approximately five million tourists visit Tenerife each year: It is the most visited island in the archipelago. It is one of the most important tourist destinations in Spain, hosting one of the world’s largest carnivals, the Carnival of Santa Cruz de Tenerife. The capital of the island, Santa Cruz de Tenerife, is also the seat of the island council (cabildo insular). That city and Las Palmas de Gran Canaria are the co-capitals of the autonomous community of the Canary Islands. The two cities are both home to governmental institutions, such as the offices of the presidency and the ministries. This has been the arrangement since 1927, when the Crown ordered it. (After the 1833 territorial division of Spain, until 1927, Santa Cruz de Tenerife was the sole capital of the Canary Islands). Santa Cruz contains the modern Auditorio de Tenerife, the architectural symbol of the Canary Islands.
