    This wall is an astonishing educational and aesthetic work. This is a stratigraphic scale made with natural stones and retracing the timeline of the geological formations of the country.

    This 54-meter-long wall chronologically displays rock layers that cover the region's geological history, from the Cambrian (approximately 540 million years ago) to the current Quaternary. Each meter of the wall represents ten million years of geological time.
