If you haven’t, the temple of the Sun Solstice in Machu Picchu is a semi-circular construction built over a strong rock, adapted to the natural environment.
On the temple of the Sun there’s a tower with a trapezoidal window, built over a rock of pure granite and in this place the persons who were in charge of the cult of the INTI (The principal god, the Sun) they keep several mummies to be worshiped.
This place is a must see attraction on you agenda, since that this is a very special place with great energy. The gate has a very interested security system, which includes many metal rings that functioned to avoid that the common people was able to watch the rituals dedicated to the sun. Take a look!
