Llactapata

Inca building at Llactapata facing Machu Picchu
Summary
On Thurs, Nov 6th, 2003, it was announced in London that an Anglo-American team, supported by The Royal Geographical Society, had found that the site of Llactapata, located in the Peruvian cloud-forest not far from Machu Picchu, was far larger and more significant than had previously been thought.
Flying over the Andes, the team had first experimented with infra-red cameras to try to see through the thick jungle vegetation and reveal the outlines of stone buildings beneath.
They had then travelled overland with a mule-team and cut their way through to the substantial site, which lies at around 9,000 ft in the Eastern Peruvian Andes.
The expedition found that the central plaza at Llactapata has ceremonial doorways aligned to Machu Picchu, the great Inca centre which can be seen in the distance. There is also a two-storey temple, which faces the rising sun.
The team was led by the British writer and explorer Hugh Thomson and the American archaeologist Gary Ziegler.

The only previous identification of the main sector of the site had been by the American explorer Hiram Bingham in 1912, but he left such an inaccurate account of its position that no expedition has been able to give a report of it since, although they have found other smaller sectors nearby (Thomson had himself been a member of one of those other expeditions in the early 1980s, as he described in his book The White Rock).
The Thomson-Ziegler expedition both re-located this main sector and also identified and mapped as many as five sectors spread out over several square kilometres across a hillside, making the Inca settlement of Llactapata a site of some magnitude overall.
In the full report they issued on the site (later published in the Revista Andina), the team members analysed the complex set of alignments between Llactapata and Machu Picchu, which suggest that Llactapata was designed as an observatory site for its larger neighbour. See full report

In particular, a remarkable long sunken passageway was discovered that runs almost 150 feet back into the hillside, without doors or exits to either side, with a sight line to Machu Picchu at its far end directly over the various valleys in between. Further investigation by Dr Kim Malville showed that the corridor was aligned so as to be exactly in line with sunrise at the June Solstice, and with the rise of the Pleiades constellation, used in the Andes from time immemorial to tell the beginning of certain agricultural seasons.
It therefore seems the Incas may have built Llactapata as a place from which they could both admire Machu Picchu and use it to take astronomical readings.
The layout of the main buildings also corresponded in a quite remarkable way with the layout used at the Coricancha, the main Sun Temple in Cuzco. It is well known from the chronicles that the Incas used the Corcanca as a template for similar smaller scale buildings throughout the Empire. See full report for detailed discussion of this.
The well-known anthropologist and explorer Johan Reinhard, who discovered the ‘ice-mummies’, commented: ‘Thomson and Zieglers’ important discovery reinforces the need to expand the Machu Picchu Historical Sanctuary’s borders to include and protect a wider area.’ At present the Llactapata ruins lie outside the protection of any Peruvian National Park and so are vulnerable to looters.
Background
The expedition was supported and approved by the Royal Geographical Society and by the Mount Everest Foundation.
The 17-strong team included an expert on archaeoastronomy, Dr Kim Malville, Professor Emeritus at Colorado University, the veteran British explorer Nicholas Asheshov, whose first expedition for National Geographic was in 1962, and the Australian explorer John Leivers, as well as Peruvian, British and American field workers. Many of the team had worked with Thomson and Ziegler on their research expedition to Cothttp://www.thewhiterock.co.uk/?page_id=336a Coca the previous year.

Location
Llactapata is approximately 50 miles north-west of Cuzco, the old Inca capital, and only two miles from Machu Picchu. One curiosity about the site is that it should be so close to Machu Picchu, which half a million visitors travel to each year, and yet have remained so unexplored.
Press
In Peru, the expedition’s report and analysis of the site was published in Spanish in a full, illustrated 11,000 word lead article by the Revista Andina, (#39), the leading Andeanist academic magazine, which also published peer-reviews of the findings by specialists in this field, Tom Zuidema, Vincent Lee, Jürgen Golte and Peter Kaulicke.

In the UK, the expedition’s discoveries were reported by the Daily Telegraph, Independent and Guardian, and in the USA by the New York Times and LA Times, along with many other publications worldwide.
Hugh also wrote a personal account of the findings for the Daily Telegraph Magazine:

Update 2009: One primary aim was to encourage the Peruvian authourities to restore and maintain the ruins which, as Johan Reinhard commented above, lie outside the Machu Picchu Historical Sanctuary’s borders and on private land. As a result of the expedition, some of the central Sector I has now been cleared and restored, and grass laid in the surrounding area - although not the sunken passageway beside it, or the other sectors, which all urgently need increased conservation.
Indeed one problem that has arisen from grassing the area around Sector I is that locals are now using the area as a pampita on which to graze cattle: the cattle are inflicting a great deal of damage on the buildings, particularly the sunken passageway which when Hugh Thomson returned with a PBS / National Geographic film crew in June of 2009 was showing significant signs of wear, as cattle were allowed to roam along it.
Another recent article in the Peruvian magazine Caretas by Nicholas Asheshov has drawn attention to this problem.
