The Plitvice lakes National Park belongs to Dinaric karst area and due to its specific geology, geomorphology and hydrology it truly is one of the most impressive karst entities in the world. Apart from dolomitic rock, mesosoic limestones with dolomite inserts prevail.
Archaeological research suggests that prehistoric settlements existed in the Park area, while ruins of a fortress of the Illyrian tribe Japodi have been found at the site known as “Gradina”. Here the Romans built watchtowers on the foundations of which a fortified monastery was later built. Its founders were most probably the Templars or the Paulines. Croats permanently settle here in the 7th Century. Turkish invaders are present in this area from 1528 to the beginning of the 18th century, when Austria established the Military Frontier, thus stopping the penetration of Turks into Europe.
On the lakefronts, herders begin to settle erecting wooden huts in the forests and clearing the land to build settlements. From these shepherds huts developed the Lika log cabin with stone cellar, and steep roof covered with shingles or rye straw.
