Motillas are old structures found in parts of Spain, particularly in the region of La Mancha. They look like small castles with walls made of rocks and mud. People built motillas a very long time ago, around 4,000 years ago. They made them to protect themselves from enemies, wild animals, and bad weather.
Motillas were usually built on a hill or a mound of earth. They have a circular shape and are composed of two concentric walls with an entrance or gate. The walls were made by piling rocks on top of one another and covering them with mud. Inside the walls, there was a space where people could live, work, and store their things. They probably had a small watchtower at the center.
The motillas were probably used by a group of people, maybe a family or a small community. Inside, they would have had a place to cook, sleep, and keep their animals. They might have used the motillas to hide when they were being attacked by other groups of people or to protect themselves during times of war. The motillas were also used as a place to store grain and other foodstuffs, which would keep them safe from rodents and other pests.
In summary, motillas are old structures that were built to protect people from harm and to keep their things safe. They were made from rocks, mud, and earth and were used by small communities for shelter, storage, and protection.
