Answer 1

One of the Incas' greatest achievements was building the amazing city of Machu Picchu. It was built on top of a mountain in Peru and is known for its incredible stone structures and beautiful views. It shows that the Incas were really smart and skilled at engineering and building things. Plus, they did all of this without using any modern tools or technology, which is pretty impressive for people who lived hundreds of years ago!
