Granite is part of the character of Dumbría. This is demonstrated by the whimsical nature of nature when it comes to creating sculptures that challenge the wind while maintaining a perfect balance. An example of a natural whim is the Pedra do Brazal, also known as Pedra Cabalgada.
Juan Ramón Vidal Romaní, Professor of Geology and Director of the University Institute of Geology of A Coruña, maintains that it is a granitic magma that 330 million years ago ascended to the earth's surface and that when cooled turned into rock, stopping at a depth of 24 km .
Since then erosion by rain, wind, and rivers has carried away the earth and the rocks that covered it, until 200 million years ago it first saw sunlight. It was a slow climb, at a rate of 5 inches per year, the equivalent of the size of a lemon per year.
The Pedra do Brazal was able to withstand the fury of natural disasters such as rain, wind and earthquakes. It has a minimum support surface of 0.5m radius supporting a weight of more than 150 tons (something like the weight of 15 African elephants… almost nothing). At the top it has concavities (sinks); something very characteristic of granite in Galicia. Its shape in horizontal layers is due to the friction of the rock when it ascended from a depth of 24km to the surface of the earth.
Anecdotally, let me tell you that the trophy won by Joaquím Rodríguez “Purito” after winning the title of the twelfth stage of La Vuelta 2012 was a replica of this whim of nature, a work created by the sculptor, based in Carnota, Nacho Porto.
