- Akapana Pyramid Mound (Tiwanaku/Tiahuanaco) Tiwanaku · Bolivia
Evidence for and against
- Engineering scholarship excerpt describes subterranean canals associated with Akapana and flow routing into the perimeter canal system
Other claims about Akapana Pyramid Mound (Tiwanaku/Tiahuanaco)
- Published book-length reporting from 1988–1989 excavations describes Akapana’s construction techniques, hydraulic system, summit ritual spaces, and offerings, framing it as the principal structure of Tiwanaku.
- A scholarly reassessment argues that key aspects of Akapana’s dating, form, and construction remain insufficiently substantiated due to past excavation/interpretation shortcomings, proposing alternative methods and reinterpretations.
- A UNESCO-linked multi-year conservation effort (2015–2018) implemented detailed surveying (TLS), sampling, stability analysis, and mitigation measures on Akapana’s east flank, with support/training for local authorities.
