Humans liked to put their homes in caves a long time ago, and this primitive way of life has become a new trend in Spain in recent years.

In the province of Granada in southern Spain, cave houses are very popular. They are not only warm in winter and cool in summer, but also have a good insulation effect.

Spain is mountainous, especially in the south. The locals have long had the tradition of living in caves. Statistics show that tens of thousands of people still live in cave houses in the province of Granada. They built their homes in "caves" that dug into the hillside. Since there is not much rain in the area, there is no danger of waterlogging inside the cave house, nor is it so humid.

Throughout history, Granada has always been populated by people living in cave houses. Whenever a storm comes, the cave house becomes a place for people to shelter from the wind and rain. Cave houses also provide hiding places in the face of large animal infestation.

With the rise of the city, cave dwellers immigrated to the city one after another, leaving a large number of cave houses idle. Later only some very poor people chose to continue living here. But now, with the development of the times and the innovation of architecture, these cave houses have become the homes of many people who advocate returning to nature, and they are loved by people again.

In recent years, especially since the outbreak, many Spaniards hope to return to nature. In order to experience the "primitive" way of life, they moved their homes into caves. A couple from Madrid came to the local tourism and were deeply attracted by the cave house. They chose to settle here and hired a construction engineering company to dig a cave house on a hillside.

The living room, bedroom, kitchen, bathroom, and storage room are all available. Some of the interior walls are painted white, and some still retain the appearance of natural stone. They laid floor tiles and floors in the house and cut a few windows on the wall to increase the lighting and ventilation in the cave house.

They modernized and renovated the cave house with original and natural decorations, and now the whole house looks unique.

A local "Some Suggestions on Using Cave Houses" wrote that the insulation effect of cave houses is generally good. In the cold winter and hot summer, the temperature inside the cave house is in stark contrast to the outdoor temperature. It is warmer in winter and cooler in summer. It is said that the indoor temperature of the cave house is generally between 14 degrees Celsius and 20 degrees Celsius throughout the year.

The couple from Madrid are very happy with their carefully crafted cave home. The hostess said that living in such a house not only has a pleasant climate but also has a feeling tone. The fusion of primitive and modern cave houses not only meets the needs of living but also brings them a unique living experience. They also specially invited some friends to visit their home and suggested that they also move here.

In addition to being used as residential accommodation, local cave houses have also been transformed into museums, shops, hotels, etc., and some hotels have dug outdoor swimming pools at the entrance for guests to relax.
