The village, built of stone and fortified with medieval walls, has the effect of a town. The hill was settled in the Hallstatt period and in the period of Antiquity. Older preserved walls belong to the 12th century and the newer to the 16th century. The village is comprised of a joined series of houses placed between terraces and roads, on the sunny side of the slope. Open areas have been arranged into cisterns with wells. The rainwater used to be collected into them from roofs with the help of stone eaves troughs. The houses are made of stone, with wood being used only for roof constructions and for division of floors.

In 1990 the area of the green Bay of Strunjan between Izola and Piran was protected as a natural reserve because of its geological and geomorphological characteristics, great biotic diversity, and the fact that it encompasses the longest unbroken natural section of coast on the entire Bay of Trieste. It occupies 160 hectares of land area. Its most remarkable part is the 80-meter overhanging wall of the cliff composed of soft flysch layers that the sea, wind, and rain constantly shape and change.
