We can see a thousand years of history in a walk through modern day Lima. The present day zoo houses not only exotic animals but constructions spanning 1500 years. From the truncated pyramids of the Lima people and the adobe mounds of the Ychsma through to the late additions of the Inca. Then the Spanish built a house on top of one of the pyramids. There is nothing unique about the grounds of the zoo, because modern Lima is still dotted with such sites, although only a fraction remains of the rich civilisations that previously lived, worked and worshipped here.
If we exit the zoo at Parque de Las Leyendas and walk round the high back end of the Huaca Tres Palos where the 98 posts were possibly used to track the motions of the sun and stars, we can walk up a modern road that separates the grounds of the zoo from the grounds of Pontificia Universidad Catolica del Peru, more usually known simply as Catolica or PUCP. When we reach the eastern end of the huaca, we are at its front, the lower end where an access ramp leads to the storage and administrative structures on top. And leading towards this access ramp from the south is a fantastically preserved stretch of road running through the university campus.
