'Renovated' pyramid may topple over

TIWANAKU, Bolivia: Eager to attract more tourists, the town of Tiwanaku in the Bolivian Andes has spruced-up the ancient Akapana pyramid with adobe instead of stone, in what some experts are calling a renovation fiasco.

Now, the Akapana pyramid risks losing its designation as a UN 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 BC to AD 1200.
