Sillustani

Massive pre-Inca burial towers built from stones too large and heavy to be lifted with known Andean tools.

What mainstream archaeology says

Sillustani is an Aymara burial site near Lake Titicaca, featuring chullpas (funeral towers) built by the Colla people before the Inca conquest.

What the evidence actually shows

The largest chullpa at Sillustani is made from massive stones that taper outward as they rise — a structural achievement that defies gravity. The finish work on the exterior blocks is smooth to a degree inconsistent with stone-on-stone polishing. A half-finished tower still sits at the site, abandoned mid-construction for unknown reasons.
