Gabion walls are the newest trend in the landscaping of the Romanian backyards and gardens. Already well-known in other parts of the world, they became popular in Romania as well for their unique appearance and their aesthetic and practically endless attributes. Also called "gabions", these structures were used for the first time in military architecture to reinforce river banks or dams. Initially, the gabions were actually baskets filled with earth and gravel, then evolved into frames filled with stones and earth, until these days when are made metallic structure filled with pebbles. So, a purely practical innovation has become an avant-garde symbol in ambient design.
