La Laguna has been a UNESCO World Heritage Site since 1999 and is considered a "unique example of an unwalled colonial city". The original 15th century layout remains almost intact, just as it was depicted by Master Leonardo Torriani in his map of La Laguna. The city was also used as a template for the colonial cities founded in America, such as Old Havana, Lima and Cartagena, which is why their houses and streets looks so similar.
