Machu Picchu: How is the floor of the citadel maintained in good condition?









The direction of the National Archaeological Park of Machu Picchu explained some special measures reduce the impact of rain on the Inca citadel.

Machu Picchu (Cusco) is visited daily by some 5 thousand domestic and foreign tourists. This great income of people to the citadel, distinguished as “the main tourist attraction of the world 2017”, by the World Travel Awards (WTA) 2017.

With the aim of preserving the citadel of Machu Picchu, these are some actions taken to maintain the patrimonial zone.

Fernando Astete, director of the National Archaeological Park of Machu Picchu, said that because the archaeological zone before had roofs (in the Inca period) and now, spaces without coverage could suffer deterioration due to rainfall.

On the other hand, according to Astete, the use of a special floor has been beneficial because if it had not been implemented, the floor of the Inca archaeological site would have collapsed by up to 15 centimeters.

“We have to make the treatment of the floors with a sloping surface so that the waters leave the enclosures, the trails have to have a work of ramming, all this is done to avoid the infiltration of water which is what could damage the most” , explained Astete about the maintenance that takes place in the heritage zone.

“The rains could structurally compromise the monument if
the rainwater infiltrates the subsoil. To avoid this, drainage systems have been operated in a better way
Inca times with contemporaries, “Astete told the Andina news agency.

Each month, Machu Picchu is visited by 150 thousand tourists, which can reach 1 million 800 thousand a year.

One of the damage mitigation tools used in Machu Picchu is the use of draining grills.

“(The draining grills) have a great durability, we have them in use for 6 years and it is not seen that they have worn out, if we had a path, without the floors, with the trampling and shoes it will erode and in a year we could have a concavity of 15 centimeters, “said Astete.
