Patallacta (possibly from Quechua pata elevated place / above, at the top / edge, bank (of a river), shore, llaqta place (village, town, city, country, nation),[1] "settlement on a platform"[2] pronounced "pahta-yakta"), Llactapata [3] or Q'ente Marka (possibly from Quechua q'inti hummingbird, marka village, "hummingbird village") is an archaeological site in Peru located in the Cusco Region, Urubamba Province, Machupicchu District.

It is situated southeast of the site Machu Picchu, at the confluence of the rivers Cusichaca and Vilcanota on a mountain named Patallacta.

[4] On his way to Machu Picchu (at: 13°13′57″S 72°25′30″W / 13.2325095°S 72.424922°W / -13.2325095; -72.424922) Hiram Bingham, discoverer of many Incan sites, passed Patallacta,[5] sometimes given the name of Llaqtapata as evidenced by the photograph of a sign from a check-point along the Inca trail.

[8] This site housed many occupants, including travellers and soldiers who manned the nearby "hill fort" of Willkaraqay, and a shrine with rounded walls known as Pulpituyuq that had religious and ceremonial functions.

In part due to these efforts, the Spanish never discovered the Inca Trail to Machu Picchu or any of its settlements.
