San Cristóbal de La Laguna

San Crist&oacute;bal de La Laguna, in the Canary Islands, has two nuclei: the original, unplanned Upper Town; and the Lower Town, the first ideal 'city-territory' laid out according to philosophical principles. Its wide streets and open spaces have a number of fine churches and public and private buildings dating from the 16th to the 18th century.
