The Huerta Montero tomb hosts a spectacle every year in the month of December, coinciding with the onset of the winter solstice. The space recreates its functions from the Copper Age as the winter season arrives and the first rays of the sun enter the burial chamber, illuminating it entirely, just as the ancient peoples had planned when they built it.

Various activities, such as observing this visual phenomenon, an open day, and guided tours of this historical site, are part of the program of events for this celebration at a site that dates back more than 4500 years.
