Whoever built the city at Machu Picchu planned it down to the very last detail. On one side stand the houses of the nobles, along with the palace and temples. The houses of the scholars, scribes and artisans are organized around the main plaza. The peaants lived further down to the slope, amid animal stalls and storage buildings.
Every part of the city is build from stone quarried right on the site, from the plateau itself. Incan masonry, with each block fitted precisely to another with no gap in between, has to this day never been bettered.
