Most of Peru’s rich history is proudly on show above the ground; towering over your head in the shape of well-preserved colonial architecture or ancient Inca sites perched high on knife-edge cliffs. However, there is even more to be found under our feet and armed with a spade and a keen pair of eyes you could be the first person to see it for hundreds of years. Dating back to the 5th Century, the ceremonial site of Huaca Pucllana is one of Peru’s cultural wonders.
