Which South American culture is known for its advanced architecture and was prominent in the Andes region?

The Inca culture is renowned for its advanced architecture and significant influence in the Andes region. They are recognized for their remarkable engineering skills, which resulted in the construction of extensive road networks, agricultural terraces, and monumental structures, including the famous Machu Picchu. The Incas utilized local stone and advanced techniques, enabling them to build resilient structures that have withstood the test of time.

The Inca Empire, at its height in the 15th and early 16th centuries, was one of the largest empires in pre-Columbian America. Their architecture is characterized by the precision of stonework, often using large stones that fit together so perfectly that no mortar was needed. This skill not only reflects their understanding of available materials but also their ability to adapt to the challenging mountainous landscape.

In contrast, while the other cultures mentioned also contributed to the rich tapestry of South America's historical development, they do not hold the same level of prominence in terms of advanced architectural achievements within the Andes as the Inca.
