The Gran Telescopio Canarias (GranTeCan or GTC) is a 10.4 m (410 in) reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canary Islands, Spain. It is the world's largest single-aperture optical telescope. [1] Construction of the telescope took seven years and cost €130 million.
The observatory began operation around 1984 with the Isaac Newton Telescope, which was moved to La Palma from the Royal Greenwich Observatory site at Herstmonceux Castle in East Sussex, England. The move was troubled, and it is widely recognized that it would have been cheaper to build a new telescope on-site rather than to move an existing one.
