Puma Punku — Tiwanaku’s Precision Megaliths

A monumental complex of ultra‑precise stonework and colossal blocks, Puma Punku stands as one of the most debated archaeological sites in the Andes — a puzzle of logistics, craftsmanship, and ancient connection. :contentReference[oaicite:1]{index=1}

Location: Tiwanaku, Bolivia

Type: Terraced platform & stone complex

Era: Middle Horizon (c. 536–600 CE)

Overview

Part of the larger Tiwanaku archaeological complex near Lake Titicaca, Puma Punku is a terraced and engineered platform mound renowned for its massive, precisely cut blocks of red sandstone and andesite. Archaeologists attribute it to the Tiwanaku civilization, active between the 6th and 10th centuries CE. :contentReference[oaicite:2]{index=2}

Architecture & Materials

The site features a foundation of massive red sandstone slabs and hundreds of andesite blocks, some weighing over 80–130 tonnes — carried from quarries miles away and shaped with remarkable precision despite a lack of iron tools or wheeled transport systems. :contentReference[oaicite:3]{index=3}

Many of the stones exhibit straight edges, smooth surfaces, and interlocking recesses that suggest a high level of skill in stoneworking, challenging models of purely hammer‑and‑chisel techniques. :contentReference[oaicite:4]{index=4}

Documented Evidence

Contributions anchor the Puma Punku narrative in measurable, sourced records rather than speculation.

Large andesite blocks with near‑perfect 90° angles and flat surfaces, carved without mortar and fitting like puzzle pieces into larger assemblies. :contentReference[oaicite:5]{index=5}

Massive red sandstone slabs from the Plataforma Lítica terrace, the largest estimated at ~131 tonnes. :contentReference[oaicite:6]{index=6}

Quarries located several kilometers from the site, demonstrating significant transport logistics across high‑altitude terrain. :contentReference[oaicite:7]{index=7}

Structural andesite “H‑blocks” with interlocking profiles that indicate systematic stone production and modular assembly. :contentReference[oaicite:8]{index=8}
