The area was a very shallow part of Lake Texcoco , dotted with tiny islands and one small island village of Aztacalco during the pre-Hispanic period . During the colonial period , the area dried up and became rural lands first owned by Hernán Cortés and then by the Counts of Miraville . In the late 19th and early 20th centuries , this area west of what was Mexico City proper was being turned into “ modern ” colonias for the wealthy seeking to escape the deterioration of city center . The colonia 's height as an “ aristocratic ” and “ European ” enclave was from its founding in the 1900s until about the 1940s . However , wealthy residents began to move to newer neighborhoods as early as the 1940s and problems associated with urbanization began to appear in the 1950s . Older mansions began to give way to modern commercial buildings in the 1960s and 1970s as the deterioration became more serious . The 1985 Mexico City earthquake caused widespread destruction in the colonia , especially to newer and more commercial and apartment buildings , even causing one major development to mostly disappear . Since then , there have been efforts to conserve the area 's architectural heritage and regain some of its former prestige with some success
