Native Americans built their own kinds of architecture. While travelling tribes built movable huts, others built longhouses. The tribes of the southwest Americas baked bricks in the hot sun for building because they did not have a lot of trees for wood.
The homes these natives built were known as Pueblos. They could hold many families and were built like a fortress to protect those inside in case of attack. Ladders were used to climb from level to level of a pueblo, and they could quickly be pulled up off the grown to keep invaders from getting in.
