Archaeologists in Spain have discovered a 4,000-year-old tomb that was designed to illuminate with sunlight during the summer solstice. The tomb was discovered in the province of Badajoz, near the Portuguese border, and is believed to be part of a larger Neolithic burial site.

The tomb is made up of a long, narrow corridor that leads to a circular chamber. The chamber is aligned with the rising sun on the summer solstice, allowing sunlight to enter and illuminate the walls. The effect would have been similar to that of Stonehenge in England, where the sun aligns with the stones during the solstice.

The tomb is believed to have been used by the ancient inhabitants of the region for funerary rituals and burials. The discovery is significant because it provides new insights into the beliefs and practices of the Neolithic people.

The tomb was discovered by a team of archaeologists from the University of Extremadura, who have been working in the area for several years. The team used remote sensing techniques to map the area and identify potential burial sites.

The tomb is now being studied by experts, who hope to learn more about the Neolithic people and their customs. The discovery has also sparked interest in the region, with officials hoping to promote the site as a tourist attraction. The tomb is a fascinating glimpse into the lives of our ancestors and further research may reveal even more about their beliefs and practices.
