Patallacta is a large Inca site near Machu Picchu, built atop stepped agricultural terraces surrounding a rising hillside.

The site sits along what is now known as the Inca Trail, which runs to the far more famous Machu Picchu and it is believed the settlement was also used by the Inca as a stopping point for those on their way to the ancient city. Sometimes referred to as Llactapata, there remains significant confusion as to the naming conventions for a number of Inca sites in this region.

Burned by the Inca as they retreated from the Conquistadors, today the remains of Patallacta, include dozens of walled houses and other buildings which can still be explored. Many tours of the Inca trail will stop at Patallacta and that is probably the easiest way to explore the site.
