For my third post I chose to do one of the new seven wonders of the world “El Castillo”.   I have visited this location 6 different times now in the past decade, and every time I see it I attempt to picture people from a civilization that had almost no technology building it.  The planning and man power needed to complete such a grand project is just not even imaginable for me.  My favorite thing about this structure is the carvings that are seen in various areas of the pyramid, and also that during certain times of the year the stepped sides cast a shadow that resembles a serpent.  I definitely recommend this location to anyone that is either interested in architecture or ancient civilizations.
