Read the article Skara Brae: Skara Brae is one of the oldest historical sites in Europe, and it stayed hidden for more than 4,000 years. The ancient village of Skara Brae was discovered on the main island of Orkney, in Scotland. A massive storm in 1850 removed the sand that had covered it for thousands of years, exposing the remains of a small village. Skara Brae is a collection of eight round, stone houses that still have their stone furnishings and even some of the belongings of the inhabitants. The contents can tell us a great deal about how people lived in what is called the Neolithic era, or the last period of the Stone Age. Seven of the eight houses appear to have been family homes, with beds, dressers, fireplaces, and even simple toilets. The eighth house may have been a community workshop. It shows evidence of tool-making and the use of a large fire pit. How was Skara Brae built, and what, eventually, happened to it

Answer and Explanation:

As shown in the text above, the Skara Brae was built with stones. Despite being in Europe and wood being more efficient as a thermal insulator for cold weather, wood was very scarce in this region, with stones being a more appropriate material to build houses, as you can see in the remains of this community. Many scientists believe that the roofs of these houses were made from whale ribs and the bones of other animals.

Historians believe that Europe's very cold weather during the winter was the reason the residents of this house left the region. In addition to the fact that their stone houses did not protect them from the intense cold, the region did not have enough food for them during the colder seasons.

It is important to emphasize that Skara Brae is considered a historical heritage by UNESCO.
