The 2nd card sent by Marco was from Querétaro, the capital capital and largest city of the state of Querétaro, located in central Mexico.
The city has preserved its historic downtown and taken steps to beautify many areas. The Historic Monuments Zone of Queretaro was named a UNESCO World Heritage site in 1996. The property was inscribed on the basis of two of its cultural criteria and considering that the site is of outstanding universal value and an exceptional example of a colonial town whose layout symbolizes its multiethnic population. It is also endowed with a wealth of outstanding buildings, notably from the 17th and 18th centuries.
Queretaro holds several treasures, and a friendly sense of civic pride prevails. The historic city center is filled with lovely colonial mansions, immaculate pedestrian alkways (andadores) and quaint plazas little changed since colonial days. - in: http://www.visitmexico.com/en/queretaro
