What are the Inca known for?All of thesebuilding with stone that fit perfectlybridgesroads

The Inca are known for several remarkable achievements:

1. Building with Stone: The Inca were master stonemasons. They are known for their impressive stone structures, such as Machu Picchu, which were built with a technique called ashlar (smooth stone without mortar). The stones were cut so precisely, and wedged so closely together, that a credit card cannot be inserted between them.

2. Bridges: The Inca were also known for their suspension bridges. These bridges were made from grass and other natural materials, and were strong enough to support the weight of the Inca army. The most famous of these is the Q'eswachaka Rope Bridge.

3. Roads: The Inca built an extensive road system, known as the Inca road system, that spanned more than 25,000 miles. This system connected various parts of their empire, which extended from modern-day Colombia to Chile and Argentina. The roads were used for trade, military movements, and communication.
