The mountain also servs as the triple border point of Venezuela, Brazil and Guyana.
Adobe bricks (mud bricks) are made of earth with a fairly high clay content and straw.
Often a clay render is applied as a surface coating.
Adobe brick building is an ancient technique common in the Americas and the Middle East.
The oldest structures in earth dating back to at least 8300 BC are in adobe, as well as some buildings around 900 years old, which are still in use.
"Adobe" is the Spanish name derived from the older Arabic "al-tob", dating from the Moorish occupation of Spain.
With adequate supervision this technique is highly suitable for owner builders, as no costly tools or equipment are necessary and the essential know-how can be easily acquired on a training workshop and through hands-on experiences.
Nevertheless it is very important to provide adequate weather protection of the earth walls, especially in exposed situations.
This is normally done with the provision of adequate eaves.
There has been a lot of research on this technique with the result, that rational engineering solutions can now be applied to structures in Adobe bricks.
Since 1998 the technique is accommodated in the NZ Earth Building Standards.
