Trovants are extraordinary rocks that grow and multiply, and they are found in Romania. They aren’t just unique because of their ability to multiply; they are composed mainly of a hard stone core and the rest made up of sand which forms around the core as its shell.

Trovants can only be made by highly-porous sand accumulations and sandstone deposits that are cemented by waters rich in calcium carbonate. The name “Trovant” (trovanti) was given by the naturalist Gh. M. Murgoci in his work “The Tertiary in Oltenia”.

WHAT MAKES THESE ROCKS MULTIPLY?
Water rich in calcium carbonate is essential in forming a Trovant, and that is also the key to make the rock grow in the presence of rainwater. After every heavy rain shower, Trovants absorb the rain’s minerals. The minerals are combined with chemicals already present in the stone that later creates a reaction and pressure inside. The pressure spontaneously makes the rock grow from the center to its margins and multiply, with a deposition rate of about 4-5 cm in 1000 years.

Trovants usually appear with smooth and edgeless shapes - cylindrical, nodular, and spherical.Trovants develop these various shapes as they grow and multiply, due to irregular cement secretion. These formations range from a few millimeters to as large as 10 meters.

Trovants aren’t only strange due to their structure and ability to grow and multiply. They can also move from one place to another. Other than that, they also have root-like extensions and age rings visible when you cut the stone, but scientists have yet to find out an explanation of these unique features.

These rocks came into existence because of earthquakes which occurred 6 million years ago. The sand reservoir was created after the successive sedimentation of detritic material transported by the rivers.

If you want to see these rocks up-close then head right away to Romania’s Valcea County. You can either go to a sand quarry near Costeşti village or along a river in Gresarea Brook nearby Oteşani village, approximately 15 km from Horezu. You can also see Trovants at the “Trovants Museum” Natural Reserve run by the Kogayon association which aims to raise awareness about protecting the environment. This museum located inside Costeşti village is protected by UNESCO.

With combined characteristics of a plant and a rock, it’s confusing if these Trovants should be categorized as living or non-living creatures. But whether alive or not, these growing stones are surely interesting to see, touch and use. Besides its popular use as a building material for tombstones, locals also use them in making souvenirs.

Apart from Romania, you can also see the growing stones in Russia, the Kazakhstan steppes, Czech Republic, and other places.
