The Guardhouse also known as the Caretakers Hut was a thatched roofed building constructed from fairly crude stones and featured 3 walls and one open long side. The Guardhouse was a building used by soldiers who guarded two main entrances to Machu Picchu. From the south there was the Inca Trail from Intipunku (the Sun Gate), which nowadays is the finish of the classic 4 days Inca Trail hike; and from the west the entrance of the main Inca trail from Vilcabamba.
The Guardhouse is one of the first attractions on the upper tourist circuit around Machu Picchu. From its commanding high position in the south of the citadel, it is one of the best places for panoramic views of Machu Picchu, Huayna Picchu and surrounding mountains. Compared to other buildings within the citadel, the guardhouse is not an overly impressive structure but due to the photographic opportunities afforded from the building, it is a must visit for anyone visiting Machu Picchu.
