In a bid to attract more tourists, the town of Tiwanaku in Bolvia restored an ancient pre-Columbian pyramid. However, they made a major mistake when they rebuilt it using adobe instead of stone.
Now, the Akapana pyramid risks losing its designation as a U.N. World Heritage Site, and there is concern the makeover could even cause its collapse.
The pyramid is one of the biggest pre-Columbian constructions in South America and a building of great spiritual significance for the Tiwanaku civilization, which spread throughout southwestern Bolivia and parts of neighboring Peru, Argentina and Chile from around 1500 B.C. to A.D. 1200.
