It was the Inca that used mortar to fit giant stones together,
it is the incas who did that. the Incans built monuments and buildings out of huge stones without the use of mortar, instead, they carved them up to match each other like a puzzle which made them extremely durable. Both the Aztecs and the Mayans used mortar.
The Inca civilization fitted giant stones together without mortar, using a technique called dry masonry. Their exceptional craftsmanship can be seen in structures like Sacsayhuamán and Machu Picchu. This skill allowed for the creation of durable and stable buildings that have withstood the test of time.
