Which UNESCO World Heritage Site in Bolivia is famous for its monumental Gate of the Sun?

The Bolivian UNESCO World Heritage Site famous for the monumental Gate of the Sun is Tiwanaku: Spiritual and Political Centre of the Tiwanaku Culture.

Tiwanaku was a major pre-Columbian ceremonial and political center near the southern shore of Lake Titicaca. Its monumental architecture includes the Gate of the Sun, the semi-subterranean temple, the Kalasasaya platform, and large carved stone blocks. The site was central to a culture that influenced a broad region of the Andes.

The Gate of the Sun is carved from a single block of andesite. Its central figure is commonly interpreted as a deity or supernatural being, surrounded by smaller winged figures and other imagery. Scholars continue to debate details of the iconography, so interpretations should not be presented as completely settled.

UNESCO inscribed Tiwanaku in 2000. It is distinct from Machu Picchu and other later Inca sites. Tiwanaku’s main monumental development predates the Inca Empire by many centuries.
