Former Jesuit Colleges in Tepotzotl

Tepotzotlán is perhaps one of the most interesting towns in central Mexico. The Convent of San Francisco Javier, nowadays the National Virreinato Museum (Virreinato being the period in which Mexico was under Spanish government, executed by a viceroy) is perhaps the most beautiful architechtural and iconographic masterpiece in the Valley of Mexico (which is a lot to say...).

If you ever travel to Mexico City, take the bypass that gets you from Santa Fe (in the Western part of the City) to the highway to Queretaro. Not far away from the first toll booth you'll find signs that will get you to Tepotzotlán. It won't take you more than an hour to get there and it's completely worth it.

Once there, do not forget to visit the aqueduct which is one-of-a-kind.

Should be included in the WH list... definitely deserves it.
