ljubljansko barje

The origins

For the making of the basin, which is today called Ljubljansko Barje, nature needed millions of years. As the Barje spreads on tectonically active area, its origin has been attributed to the sinking of bedrock. Into this depression flew numerous karst underground waters and streams, bringing shingle and other sediments with them. The Sava river brought with it huge quantities of gravel, virtually damming the Ljubljanica river where it joined the Sava and inundating the entire Barje basin at the same time. Through millennia, the lake was gradually filled up by the river's alluvial deposits, until the lake with its pile dwellers dried up some six thousand years ago and enabled the origin of large marshes and eventually raised bogs and fens.
