The Trovant stones of Romania, found in Costești, are remarkable for their ability to grow, move, and reproduce. Formed millions of years ago, these unique stones expand after rainfall due to a chemical reaction with minerals in the water. Over time, small stones called “microtrovants” form on the surface of larger ones, eventually breaking off to grow independently. These mysterious "living stones" continue to fascinate scientists and tourists alike, with research ongoing to uncover their secrets.The Trovant stones of Romania, found in Costești, are remarkable for their ability to grow, move, and reproduce.
